American girl Nina gets off to a bad start on her first day of boarding school. Her new roommate Patricia is upset that Joy, her old room mate has disappeared without any farewells. Finding that Nina has taken her place just makes things worse.

Fabian and Amber confront Patricia about allowing Nina to come out of the attic; however, Patricia has thrown the key out of the window into the bushes. While hiding from Victor, Nina accidentally opens a secret panel in the attic with her locket and sees a pair of mysterious eyes looking out at her, causing her to panic. In the end, she uses a hairpin to pick the lock and leave the attic. She successfully finishes her "initiation ceremony" and later confides in Fabian about the eyes. The next day, Fabian asks Nina to walk with him to school, and on the way there, they recover the key and Nina decides to keep it for future trips into the attic - "the only place where she truly felt welcome".

Patricia reports Joy as a missing person to the police. After looking up the hieroglyphic symbols on the back of the old painting, Nina and Fabian conclude that the treasure is hidden under the eighth stair, and they manage to crack the code leading them to the staircase where they find the next clue - a key. Fabian makes Jerome reveal his plan to Mick and this makes it so that Amber and him are back together - at the expense of Alfie. Mick and Amber decide to have a getting together party that night and invite everyone to attend.

Victor rigs the attic door with a feather, and when Nina and Fabian sneak up to find some strange wax cylinders (during Mick and Amber's getting together party), Victor knows that someone has been up there. Mara talks to Patrica in the girls bathroom about her liking Mick, and unknowing to the two of them, Amber hears the whole thing - eventually being fed up. Amber blows up with jealousy over Mara and Mick's friendship and demands to change rooms, sharing with Nina instead of Mara. Fabian and Nina take the wax cylinders to Fabian's uncle Ade who runs an antique shop and find out about the phonograph cylinders. Fabian remembers seeing an old phonograph in the attic. They resolve to return to the attic if they want to play the cylinders. Patricia overhears Victor talking to the Sergeant from the police station about Joy, and realizes the police are also involved in the conspiracy surrounding Joy's disappearance and becomes afraid of everything.

Mara cheats on Mick's French test for him, which Jerome sees, and Jerome uses it to blackmail her into doing chores for him and Alfie. Nina and Fabian sneak back into the attic to listen to the cylinders but it makes a loud screeching sound and they have to abandon their plans. Patricia sees someone hanging around on the school grounds and is freaked out, thinking it is a ghost. She confides in her Drama teacher, Jason (Mr. Winkler) who says he'll help her solve the conspiracy surrounding Joy's disappearance. Amber catches Nina with the puzzle piece and forces her to tell all about the quest for Sarah's treasure. While Nina and Fabian visit the attic they listen to the cylinders, Amber sneak into the attic and follows them.

Mick finds out Mara cheated for him and falls out with her. Amber discovers a secret message written behind the wallpaper - "Help me, Sarah Frobisher Smythe." Fabian, Nina, and Amber record the cylinders onto a Dictaphone. The young girl on the recordings mentions a murder. They suspect that the girl may be a young Sarah. Amber and Nina go to the old people's home to visit Sarah and confirm that she is, in fact, the girl from the recordings. Amber comes up with a name for their gang - "Sibuna" (Anubis backwards). They make it official with a ceremony by the woods after which Fabian manages to open the puzzle piece, revealing a riddle. Meanwhile, Jason finds Joy's broken mobile phone at the school bins; he searches for more clues but finds nothing. Guest Star: Francis Magee

Patricia meets her "ghost" again in the woods; however, this time they talk and he informs her that he is a private investigator by the name of Dr. Renee Zeldman and that he will help her find Joy. Mick rudely breaks up with Amber after she skips too many dates. Jason's investigations lead him to a meeting with Victor, and he emerges from the meeting as a changed man. After Alfie and Jerome record over the Dictaphone, Sibuna returns to the attic to re-record the cylinders, where Amber accidentally solves the first puzzle piece's riddle.

Patricia spots Nina's necklace and recognizes it as the Eye of Horus and calls Rufus to inform him that she has seen the Eye of Horus. Sibuna opens the next puzzle piece to reveal the second riddle. They work out that it refers to a fireplace, so they begin to check every fireplace in the house. Meanwhile, down in the cellar, a strange ritual is taking place involving Victor, the teachers and a select few others. The teachers confiscate Patricia's phone and find out that she is in contact with Rufus Zeno - a man known to them as "The Betrayer". Sibuna manages to open the old stove in the kitchen with Nina's pendant, and it leads them down into the cellar where they find the next clue - an old tethering ring with a code on the inside. While inspecting it, Victor comes down; they manage to hide in an old cabinet, and from their hiding place see him drink a strange liquid and toast to "life."

Amber and Nina find a black cat which has escaped from the cellar. Amber pretends that she is sick and takes the day off school to look after it, but it disappears while she is asleep. Patricia persuades Nina to go and meet Rufus to show him the pendant but when they get to the meeting place they witness Victor kidnapping an apparently unconscious Rufus, which makes them suspicious. Sibuna lets Patricia in on the secret, and debates the possibility that Victor might be drinking an elixir that gives him eternal life. They decide to use the school play to try and expose Victor. After finding evidence of sinister experiments in the cellar, they turn to Trudy for help; she forces Victor to open the cellar only to reveal that he has moved everything. To the house's horror, Victor fires Trudy.

With Trudy gone, Victor installs security cameras to spy on the kids. Mara challenges Mick to a sports quiz and defeats him; having proved herself, she offers to help with his training program. Nina finds an article on Tutankhamen's treasure and the original owners of Anubis House, who were implicated in stealing something from his tomb that was never found. After pressure from Mick's Dad, Victor removes the cameras and reinstates Trudy. The next riddle leads Sibuna (which now includes Patricia) to look underneath the stairs for something "beleathered and clasped" and there they stumble across a couple of photographs of Victor from 1925 looking exactly the same as he looks now. Guest Star: Francis Magee

The security cameras are removed and Trudy returns to the house. Mick excels in training thanks to Mara and the two end up kissing. Sibuna returns to the cellar to find proof of the elixir, and come face to face with something terrifying - a pair of zombies. Alfie and Jerome admit that they were the "zombies" down in the cellar. Later they get into trouble with Jason for conning the younger years into paying to audition for the school play. Patricia hides the elixir sample they took from the cellar, while Nina visits Sarah who tells the former that she and Rufus used to play together as children and she also seems to suggest that Victor killed her parents. At the end of the episode, Mara overhears Mick saying that he could never see himself with Mara, upsetting the latter.

Mara changes her appearance (and personality) to try and impress Mick and not be "boring"; she ruins Mick's sports gear by putting a red sock in the dryer with it. Alfie gets trapped in the cellar while going back to retrieve his zombie mask. Jerome is caught near the cellar by Victor and is sent to his room, unable to rescue Alfie who sees something traumatic in the cellar. Jerome enlists Fabian's help to rescue a shaken and traumatized Alfie from the cellar. The next day Alfie hyperventilates while trying to remember what happened, and Nina accidentally gives him the elixir from the cellar to drink. He collapses and is hospitalized. Nina feels so guilty that she quits Sibuna, handing her locket to Fabian

Victor announces that Alfie drank cleaning fluid. Nina tries to distance herself from Sibuna but still can't help solving the latest riddle leading them to an old "beleathered and clasped" dictionary which can only be opened with her locket (also, the locket only works when Nina wields it). While visiting Alfie in hospital, Patricia finds Rufus in a catatonic state. Patricia rescues Rufus from the hospital and hides him in the woods where he meets the others and warns Nina to give the locket back to Sarah. The gang manages to read a secret message hidden in the dictionary which gives them their next clue. Unfortunately, while Nina and Fabian are cracking the clue, Victor catches them and forces them to hand over the next puzzle piece.

A jealous Mara sends untruthfully incriminating pictures of Mick and his new training partner, Esther (the health and physical education teacher of the school), to Mr Sweet, forcing Principal Sweet to sack the innocent teacher. After reading a book given to them by Fabian's Uncle Ade, the gang works out they could be searching for the Cup of Ankh, and they plot to steal the puzzle piece from Victor's safe. Then, during the opening scene of the school play, Patricia spots Joy in the audience. Patricia manages to decode her unusual good luck card - a secret message from Joy arranging to meet after the play. Whilst everyone is at the play, Nina attempts to break into Victor's safe to steal the puzzle piece back - she is scared when she hears Victor returning to the house.

Nina successfully completes her mission, and finds another relic. She hears Victor saying he will "eliminate" someone in the audience. When she tells Patricia and Fabian this, Patricia thinks he is going to kill Joy; however, he meant Rufus. At the end of the play, Joy reveals herself by accident, and Victor chases her. He finds her and calls her the "Chosen One". Patricia looks at her card saying "Meet me tonight. Nine. Clearing in the woods. Joy." She meets Rufus there and he kidnaps her making Nina think the battery on her phone is dead.

Having kidnapped Patricia, Rufus attempts to blackmail Mr Sweet and Victor's followers - known as the Society of Ankh. Mara is worried, and she wants to talk about Mick breaking up, but Patricia seems to no longer be able to make time for Mara - especially since she joins Sibuna. Nina and Amber follow the clue on Joy's good luck card, spot Rufus's van in the clearing, and follow its oil leak to the warehouse where Patricia is being kept prisoner but when they go in there they get locked themselves.

Mick and Mara make up. Mick leaves the house. Fabian rescues Nina and Amber, and then Nina, Amber, and Fabian rescue Patricia with the help of Mrs. Andrews. Rufus escapes and is confirmed to be an antagonist. Nina, Amber, Fabian, and Patricia video chat with Joy when Victor says he'll give them "answers".

Patrica confronts Amber about ratting her out to Nina. The Alfie gets his blood test results back from the hospital which Fabian and Nina read when they sneak into Victor's office. It turns out that the elixir was really just an herbal concoction. Mara and Jerome become closer and start to hang out more. Jerome starts to hang out with Mara more than Alfie and it is revealed that he has a crush on her, even nominating Mara to become the school representative. Fabian loses a puzzle piece when he shoves his bag away when he thinks there will be a bag search.

The contest for School Representative heats up, with Mara running. Jerome asks Mara out, but gets rejected when he starts insulting Mick. The latest riddle leads Sibuna to the grandfather clock, but when they open it, it is found to be empty, making it seem like someone has already taken the puzzle piece. Alfie is still fishing around so the gang tells him he was right all along about aliens. Then, during a Sibuna meeting, Nina opens the 5th puzzle piece and a secret message appears on the wall of the house itself.

Amber decides to compete against Mara in the school elections. Mara begins focusing her attention on Mick - much to the frustration of Jerome. Sibuna decides to return to the cellar in order to collect a sample of the elixir, with Alfie insisting that he should go alone to prove himself. While down there, he has a terrifying flashback to the night he was trapped. Victor is suspicious when he discovers the gang were helped in their school play research by a woman called Sarah. He finds a clue in the signing out book which leads him to the old people's home and comes face to face with Sarah. Alfie tells the gang he remembered the teachers' spooky rituals from the cellar, and they discover the next clue hidden inside a fake phonograph cylinder in the attic.

Victor has Sarah stop by the house. When she sees him, she calls him a murderer, but then has various flashbacks from the past when she used to live in the house, including one in which she and Victor had been friends. Victor's father, Victor Rodenmaar, Sr. (who looks exactly like Victor) is portrayed to be cruel and unloving to his son, threatening to put him in the orphanage if he did not get the information that he wanted from Sarah. Meanwhile, Jerome shifts his allegiance to Amber's campaign.

Mara is furious that Mick cheated for her in the school elections. Nina attends Sarah's funeral and then witnesses a confrontation between Rufus and Victor at the care home. She hears them mention Joy being the "Chosen One" before they realize that she has been eavesdropping. Victor tries to find out how much Nina knows, but she gives nothing away. Later, she leads an expedition down to the cellar where Sibuna witnesses a meeting of Victor's society. Meanwhile, Patricia calls Joy to find out if she knows more than she is saying.

It is Nina's unlucky day when Victor padlocks the attic door to stop her going up there again after seeing her go in. Victor even catches Nina doing something, which ruins everything. She does not even know the worst part yet - Jerome has contacted Rufus by getting Rufus's number off Patricia's phone and is now spying on Sibuna for Rufus after being bribed. Sibuna plan to go down into the cellar to collect some of the elixir and to try to crack the latest clue. Alfie draws the short straw, but this time he will have a walkie talkie to maintain radio contact. However, Jerome secretly sabotages the whole mission by taking Alfie's walkie talkie. He almost gets caught by Victor twice and manages to escape the second time by hiding in the sarcophagus. Jerome shuts and locks the sarcophagus with Alfie still inside.

Jerome poses as Alfie's savior after his failed cellar mission by reopening the sarcophagus. He demands that Alfie repay him by secretly passing him information on Sibuna. Nina works out that the next puzzle is inside the chandelier. Amber distracts Victor by pretending to faint so that Nina can get the relic. Mara and Mick finally kiss and make up. Alfie and Jerome fall out when Jerome accidentally reveals that he is working for Rufus. Fabian and Nina near the end of their search but still have one more place to look for the last puzzle piece, which is in the stuffed black crow in Victor's office. Written on the last puzzle piece is "END." Nina begins to hear voices and when she tells Fabian about it, he questions if she's truly the Chosen One, and not Joy. This scares Nina and she gets defensive about it.

Victor grows frustrated with Sibuna and concocts a scheme to put a stop to their quest. He secretly releases mice in the house to give him a reason to search the bedrooms. He searches and finds the elixir and some of the students' proof. He also finds the panel in the attic that conceals the picture of Sarah. While this goes on, the students must spend the night at the school. Under the guise of needing to place the order for a take-away dinner, NIna and Fabian lure Trudy and Mr. Sweet into his office and lock the door. Victor is forced to abandon his search of the house in order to go and let Trudy and Mr. Sweet out.

Jerome gives Rufus Alfie's puzzle piece, much to the dismay of Alfie. Meanwhile Fabian works out that the puzzle pieces may actually be the seven pieces of the Cup of Ankh. Sibuna goes to put the Cup together when Alfie admits to letting Jerome give the piece to Rufus. Jerome is scared of Rufus and agrees to get the piece back by trying to lock Rufus in the cellar. The plan backfires when Jerome has to go down with Rufus, instead of Rufus going down by himself. They call Victor like they had planned and he goes down to be surprised by Rufus who has drunk the elixir. Jerome manages to escape while they talk, but just as Nina is about to close the passageway, Rufus grabs her arm to stop her.

Rufus escapes and Jerome asks Nina to protect him from Rufus. Amber receives her first invitation to the prom - a message on her profile from "King Tut". She reckons it is a boy with a thing about Egyptology and worries that this means Fabian. She tells Fabian and he says he hasn't asked anyone. Nina arrives and he gets nervous. Then Amber realizes "King Tut" is full of himself and thinks it is Jerome. Jerome makes a joke about it and embarrasses her in front of the house.

Mara is upset when Mick gets a new trainer. Jerome & Patricia visit Alfie in the hospital but Patrica meets an unexpected patient there.

After Patricia rescues Rufus from the hospital, he disappears. Amber attempts to help Alfie remember what happened in the cellar by hypnotizing him. Nina & Fabian solve the next part of the mystery but have their reward confiscated when Victor catches them.

Just before the play opens, Nina and Fabian learn what the "treasure" that they are searching for might be. While Victor is watching the play might be the perfect time to retrieve the confiscated puzzle piece from his safe but there's more than one unexpected visitor in the audience...

Mick finds out about the pictures and fears he may be expelled. As the play begins, Nina slips out to retrieve the puzzle piece from Victor's safe. Mick and Mara kiss onstage and realize they have feelings for each other. Patricia receives a message from Joy. Nina makes a surprising discovery in Victor's desk but becomes trapped when Victor returns unexpectedly.

Nina sees Victor open the safe. Mr. Sweet calls to tell Victor that Rufus is in the audience and Victor rushes back to the play. Nina recovers two puzzle pieces from the safe. As the play ends, Victor spots Joy in the audience and chases her.
