A burglary at detective Ben Slachter's home ends fatally for the intruder. His partner, Stan Vroom, supports his colleague unconditionally, but is he telling the whole truth? Amsterdam’s Public Prosecutor Hein Berg disrupts a key witness case and relocates to Rotterdam, where they hope he’ll be better suited for teamwork. His first case involves two hooligans who take detectives Dries van Weelden and Esther Wegereef hostage in an attempt to obtain 5 kilos of cocaine. The plan fails, but when the hooligans reveal they need the drugs because their sister is being held by dangerous criminals, Berg must decide how the team will work to free the girl.

A detainee in a forensic psychiatric facility has escaped during a trial leave. Dries once arrested this man for abusing and torturing his girlfriends’ daughters, and now, together with Esther, he is determined to get him back into the facility. Meanwhile, Ben is suspended, and Stan is assigned a new partner, Lieve Jansons, to investigate the disappearance of a notary. Stan is less than thrilled about his new colleague, as he’s worried about his suspended partner, Ben, who has become unreachable, caught up in his own agenda. When Stan finally meets Ben at a restaurant, the evening turns into a nightmare.

In a reformed community, a 15-year-old girl goes missing. Dries and Esther, who knows the community well, investigate the case. Clues quickly emerge that convince Esther the naive girl has fallen victim to "loverboys," but Dries isn’t so sure yet. Meanwhile, Stan and Lieve follow up on the street robbers Lieve had previously apprehended. Stan, however, is too preoccupied with thoughts of Ben, prompting Lieve to continue the investigation alone. But is that a wise decision?

A potential attack puts the entire team on high alert. Strong evidence suggests that two girls plan to detonate bombs in the city that afternoon. All available units are mobilized to prevent a disaster. They identify who the girls are, but it becomes a race against the clock. Can they succeed, and at what cost?

A mother reports that her son is still inside a museum after closing time. When the alarm goes off, security assumes it’s triggered by the boy, but it turns out a highly valuable painting has been stolen. Dries and Esther quickly discover that the mother lied—her son was kidnapped, and she was forced to tell this story. The child is found soon afterward but is heavily drugged. Dries and Esther discuss the case with Hein Berg, who believes the kidnapping is the top priority, but an insurance representative, a former policeman, disagrees. Meanwhile, Stan and Lieve investigate the brutal assault of a gay man who was attacked after leaving his favorite bar.

Dries and Esther investigate the murder of a wealthy Rotterdam man, who appears to have been a victim of date rape due to his online meetings with strange men. However, he was estranged from his religious family, and not everyone there seems to be telling the truth. Meanwhile, Stan and Lieve handle a report from a banker whose car and house have been vandalized. As he is responsible for managing overdue payments at the bank, a number of people emerge as possible suspects. When the banker also goes missing, all alarms go off.

The entire team intensifies its focus on the supposed suicide of a victim connected to the missing banker. But was it really a suicide? And did the banker disappear because of one of his bankrupt clients? As they delve into the banker’s dealings, it becomes clear that he hadn’t always acted ethically or honestly. Not only did he make money for the bank, but he and his friends personally profited significantly as well.

A truck driver reports his suspicion that certain shipments he transports from the port contain cocaine. He approaches the detectives to catch the perpetrators red-handed. However, it’s up to Prosecutor Berg to make the final decision. Berg hesitates to put a civilian at risk, but the driver and detectives push for the plan. Eventually, Berg agrees, though whether it's a wise decision remains to be seen. Meanwhile, Stan begins to realize there’s more going on with his former partner Ben, and that the mysterious Van Nieuwerbroek is involved. Officially, however, he can’t take any action against him.

A young Polish woman is found dead behind the greenhouses in the Westland, with an autopsy revealing severe injuries. Initial evidence points to her employer, known for making advances toward his young female employees. However, when it’s discovered that she was picked up the night before her death by a shady figure in an expensive car, the investigation takes a turn toward a more dangerous world. Meanwhile, Stan finally gets the chance to apprehend Van Nieuwerbroek.

Van Nieuwerbroek is released on Hein Berg’s orders. When Van Nieuwerbroek is found murdered the next day, Stan becomes the prime suspect. Hein and Lieve suspect that the mysterious Hunter Vaals may be involved in the murder of former colleague Ben. Hein assigns Esther and Dries to find out who Vaals is, a task that proves to be more dangerous than they anticipate. Meanwhile, Stan seizes an opportunity to leave the detention area after an interrogation by the National Investigation Service. He knows he must warn his colleagues, but he may already be too late.
