They all attend Beacon Hills High School. When Mischief Night starts, five of them go into the school to set up their pranks before anyone else. They happen to meet their sixth member of the friend group at the school. Derek questions why they're partaking in such an annoying tradition and goes to leave, only to find the door locked. He blames Scott and the others until they realise they're trapped with a psycho. They work together to escape, continuously getting split up before they have one final showdown. But who will live through it?
FYI, in this one, Derek is one year older than the rest.
