At the local cinema, an audience watches a Spaghetti Western matinee. During the film's on-screen climactic duel, a bullet is fired into a patron. With no leads and a theater full of suspects, police investigators lock the doors, put everyone back in their seats, and run the movie again. But will this shot in the dark reveal the real killer?
