1984 film by Francesca Comencini

A microcosm of people lost in search of an artificial happiness, which leads them to steal and prostitute themselves for the short ecstasy of a squirt of heroin in the veins. Marco and Pina live in this world of drugs, prostitution and violence, and they must fight for their survival. One day one of their friend dies during a holdup. Marco and Pina are helpless and will do anything to escape, but fate does not want a similar world. Between bites of heroin and sidewalk they are in a deadly trance.

After a nuclear holocaust, as the rest of society regresses to primitivism, a small, "elite" group that has managed to escape radioactive contamination takes it upon itself to exterminate those it sees as "unfit", including certain members of its own group.

A group of people are trapped in a West Berlin movie theater infested with ravenous demons who proceed to kill and possess the humans one-by-one, thereby multiplying their numbers.
