To add to his mother's (Zelda Rubinstein) human eyeball collection, recently fired orderly John (Michael Lerner) goes on a killing spree. While watching the tale unfold on a movie screen, one crazed viewer (Àngel Jové) begins imitating the action by taking the lives of other audience members. Directed by Spanish filmmaker Bigas Luna, this twisted horror film alternates between the two gory slasher stories.
