While young Cheryl is riding the West Berlin subway, a strange man in a metallic mask hands her tickets to a movie at a newly renovated theater. She invites her friend Kathy to go with her, and they meet up with 2 young men in the lobby. A pimp and 2 of his girls are checking out displays in the lobby, one of which is a demon mask from the film. One of the prostitutes tries on the mask and is cut while removing it. While the film (a violent horror movie) is starting, the woman's wound starts oozing green slime...and in seconds she becomes a hideous, fanged & clawed demon! She attacks anyone who crosses her path, and soon the theater is filled with people turning into demons - and those trying to avoid attack. The theater exits have disappeared. Even stopping the film doesn't help, as newer demons appear. Cheryl & George (one of the young men) start a desperate battle for survival, as George rides a motorcycle wielding a samurai sword through the theater, killing demons as he goes. But will the two of them succeed in escaping the evil demons who now inhabit West Berlin's streets?—Derek O'Cain imdb.com
