I Can't Sleep (1994)

Evil exists where least expected.

In 1980s Paris, a series of murders captures public attention. Meanwhile, the gorgeous Daiga moves from Lithuania to Paris, immigrant musician Théo struggles to raise his young son, and Théo's brother, a gay transvestite named Camille, sings and dances in a cabaret for a living. All three grapple with isolation and the problems of modern living, but one of them could be so desperately alienated that they have a hand in the serial murders.
