Squeaky-clean Martina Ramirez is about to commit her first crime with a group of six schoolmates—breaking and entering into an abandoned movie theater. The trespassers soon find themselves trapped inside, and while trying to discover a way out, they are startled by a projector playing a film on its own. It shows a vintage episode of a horror series, and one of the group is trapped within the film. The only method of escape is to survive the episode, but the story doesn’t play fair. As the night wears on, the projector displays more episodes, ensnaring the others one by one. Martina tries to help her classmates, hoping that they’ll trust her. However, the events onscreen continue to work against her. And when Martina’s turn arrives, she must face her own ominous trial…alone.
