Four mismatched year ten students - Andy, Felix, Jake and Sam - are unwillingly grouped together for an orienteering exercise in the rugged Bremin Ranges, on the outskirts of their hometown.
The boys are shocked that their families and friends no longer recognise them. Andy believes it's because their families have experienced a collective amnesia, but he can't explain the other strange events.
Andy, Felix and Jake break into Bremin High searching for proof of themselves in the school records; Sam searches for his girlfriend Mia; and the Thing that stalked them makes a scary return...
After the boys survive a freak storm, Felix believes dark magic is at work so he buys an amulet for protection. Andy is convinced the boys are in a state of unconsciousness.
Felix hangs out with his 'once brother' Oscar, only for them to be attacked by malevolent bees. Meanwhile, Jake realises that Bremin's Sergeant Gary Riles is the new world incarnation of his deadbeat dad.
Jake and Andy do some 'free shopping' at a milk bar but are caught by Sergeant Gary, so Jake sacrifices himself so Andy can escape. Reunited at the hideout Sam, Andy and Felix come under siege by demonic crows.
The boys return to school. While Andy deals with being the 'golden-boy', Jake re-establishes himself with his old friends, Felix bonds with Oscar, and Sam struggles with loneliness for the first time in his life.
The boys believe Phoebe could be the reason they are in this parallel universe. The boys split up; Felix and Sam follow Phoebe, while Andy and Jake head into Arcane Lane to see what secrets they might uncover.
The boys return to Bremin Ranges to replicate the first excursion in a bid to get back home. However they question whether they are better off returning to the old world or staying in this new universe.
When Felix shows Phoebe evidence of Alice, her belief that Felix can bring Alice back is reignited. Meanwhile, Mia is possessed by the Demon and convinces Sam to destroy the talisman.
When the boys encounter their mothers, they are shocked when their mothers suffer a severe allergic reaction to them. Now magic and science come together when Felix finds a spell he believes will save them.
As the fallout from Felix's betrayal threatens to tear the boys apart, Felix learns that Oscar is 'the fifth element'; the missing ingredient needed to reactivate the talisman and bring the boys home.
The demonic Bates and Oscar take Felix to the forest and construct the familiar spiral centrifuge signalling the arrival of a furious storm. Will Sam, Jake, Andy and Phoebe reach Felix in time?
