Lock In(2008)

They thought they were alone...they were wrong!

Lock In is a slasher film that transforms a high school senior prank into a nightmare. When students stage an elaborate lockdown on campus for the night, they become trapped with a vengeful killer from the town's dark past. As the group is picked off one by one, the survivors must confront a psychopath whose identity harbors a shocking twist. The film channels the gore and tension of 1980s slashers, delivering genuine scares through its relentless cat-and-mouse game. What begins as a night of costumes and pranks descends into a brutal fight for survival, with the killer's motivations rooted in long-buried secrets. Lock In combines classic horror tropes with a mystery that reframes everything viewers thought they knew about the attack.
