It's been six months since Ryan and his friend got trapped on The Island so they build a raft but they got caught in a storm, the raft broke and they ended up on a new island and separated from each other. Josh and Ryan soon finds each other trapped in a hole, Jarrah and Gabe also finds each other and later Jarrah and Gabe find Zuke. Lilly and Em are also together but Natasha and the mystery girl (from the last episode of Trapped). Ryan and Josh get saved out of the hole by a girl named Saskia who's also trapped on the island but can you trust her?

It's morning, Lily and Em goes out to find the others but when they take a shortcut over a field most covered in mud, Lily gets mud in her eye and tells Em to quick go and get water but instead of water, she finds three strangers in masks who starts to chase her. Meanwhile Josh starts to becomes friends with Saskia but Ryan is still not sure if he should trust her since she tried to steal the antidote.

Gabe went away to get some fruit but instead, he found the strangers in masks but he doesn't tell Jarrah and Zuke but later the strangers kidnap Zuke. Lily and Em are finally together with Ryan and Josh but Saskia is also there and she seems to know the strangers in masks.

The strangers in masks has captured Ryan and his friends (Natasha and mystery girl not included) with some assistance from Saskia and they have been captured in a cage in a camp full of kids and no adults. Saskia has stolen the antidote so later when Ryan has escaped he gets a disguise and come back to the camp to save his friends and get back the antidote.

Ryan has the antidote again and he has also decided that they are going to stay at the camp for a while. Later they participate in a ritual and during the ritual, Ryan and his friends find out that the other kids in the camp also are kids to scientists who Dr Hamilton has imprisoned.
