Demons

On the Berlin subway, a mysterious, masked man offers university student Cheryl two tickets to a free screening at the Metropol, an isolated and recently renovated local cinema. Cheryl talks her friend Kathy into going with her; at the theater, they meet two preppy college boys, George and Ken. Other attendees of the screening include a blind man and his guide daughter; a married couple; a boyfriend and girlfriend; and a pimp named Tony along with his two prostitutes. One of the prostitutes, Rosemary, scratches her face with a bizarre mask that is on display in the lobby. The film being shown is a violent, disturbing horror film about four teenagers who discover an old tomb and dig up the grave of a sixteenth-century fortune teller called Nostradamus. When the teenagers dig up Nostradamus's coffin, they find no body and instead an old book and a mask identical to the strange mask in the lobby. When one of the movie's characters puts the mask on and is scratched by it just like Rosemary was by its doppelganger, he then turns evil and slaughters his friends.

Feeling ill, Rosemary goes to the bathroom, where she transforms into a bloodthirsty, red-eyed demon like the one in the film. Rosemary attacks her friend, Carmen, who then transforms into a demon in front of the rest of the cinema-goers. The group of uninfected people race to any exit they can find, only to find that they have all been bricked up making escape impossible. Although they attempt to barricade themselves in the balcony, many are attacked and infected by the demons. One of the demons escapes into the city when four punks break into the building through a back entrance; the punks are soon transformed into demons as well.

In the cinema, only George and Cheryl remain uninfected. Using a display motorcycle and sword props from the foyer, they ride through the auditorium, slicing down many demons. George kills nearly all of them when suddenly, a helicopter crashes through the roof. George and Cheryl use an emergency grappling hook and winch to climb to the roof, where they are attacked by the mysterious man from the subway. They are able to kill him by impaling his head on an exposed bit of rebar. The two climb down to the street and discover that the demonic infection has spread throughout Berlin. They are then chased by a horde of demons before being picked up by a jeep of well-armed survivors. As they drive out of the city to safety, Cheryl (having been infected at some point in the theater) transforms into a demon. But before she can harm George, one of the survivalists shoots and kills her. As Cheryl's body collapses into the roadway, George (the only survivor of the cinema) and the survivalists drive out of the city.

Several people are invited to join the opening of a new movie theatre. As the horror film shown to the guests gets more and more violent, the people start to transform one by one into bloodthirsty demons. The remaining guests begin the desperate battle for their lives.
