Plot

The guys continue to investigate their "disappearance" by searching the school records, Sam finds clues of his existence from their usual timeline and finds his doppelganger.

The boys' survival instincts kick into gear as they scavenge for food and set up a home in the derelict shack. What proves more difficult is coming to terms with their loss of identity. It's one thing to be forgotten, but it's starting to look like they never existed. Andy, Felix and Jake break into Bremin High searching for proof of themselves in the school records. All they find is the dismaying confirmation that no evidence exists of them ever being students there. Then the upside dawns: nonexistence means absolute freedom. To celebrate this realisation, the boys run riot in the gym, unaware of a security camera filming their destructive fun. Meanwhile, Sam finds a romantic carving made by himself and his girlfriend, Mia, only a month before. Buoyed by what he considers to be tangible proof that he exists, Sam searches for Mia to confirm his identity. His hopes are crushed when Mia doesn't recognise him. Nevertheless, the presence of the carving gives the other boys hope that there is still some semblance of them in the world. Perhaps the effects of their 'erasure', if that's what it is, can be reversed? Jake convinces Sam to show Mia the proof in the hope that it will jog her memory. Sam returns to Mia and shows her a photograph of the carving. When Mia reveals that she made it with her boyfriend, Sammy, Sam is stunned to find himself facing off against a smarmy younger version of himself. A desperate Sam confronts his mother, Dee, but like everyone else, she still doesn't recognise Sam at all and, worse still, suffers a violent physical reaction to him. Gutted, Sam returns to their hideout to join his new, mismatched family. If these setbacks aren't enough, the 'thing' that stalked the boys in the forest makes a scary return.
