Kate is playing a new game, Pirate Islands, for her father as a test run. Sarah and Nicholas show up, but then lighting strikes there house, and the three of them get trapped inside the game. Now the only way they can escape the game is either finding the pirate's treasure, or by using the scanner which trapped them inside the game. There is just one big problem, Captain Blackhart stole the scanner, and the only way these three can get it back is by having Mars, the character Kate used to control help them out.

Kate, Nicholas and Sarah begin by trying to feed themselves cocunuts, but they can't cut them open. Meanwhile Captain Blackhart tries to figure out the powers of the scanner Kate nrought into the game. He determines that the only way to discover these powers is by capturing Kate, so he sends a group of pirates onto main island. While Kate, Nicholas, and Sarah try and hide from the pirates they run into the castaway kids who tell them there are no hiding places. Nicholas doesn't believe them, so he follows them and sees them jump into a node. He returns and tells Kate and Sarah, but they just want to get the scanner, so Nicholas decides to jump through the node himself. The node takes him to Castaway Island where he encounters a plant that begins wrapping him up and choking the life out of him.

Kate begins by bringing more water up to the tree house. It would appear that all water can be drunk on Pirate Island without having to boil it to purify it. As Kate arrives she finds Nicholas and Sarah searching the tree house for tools. They find a shovel and a pick (which need to be used to find the treasure), and Kate finds a hidden chamber which contains some wet boots. They also test their cell phones and find that they will work, but only inside the game. Kate decides to find out what the boots will do, so they go down to one of the springs and find out that the boots are a power up that allows a person to walk on water, but the power up has a limited usage on time, and when that time expires Kate falls into the spring, and it is revealed that she can't swim that well. Mars mysteriously appears and offers to teach Kate how to swim, but she pushes him into the spring, and then they take off for the tree house. Mars tries to follow them, so Kate pushes him in again.
