Law students, Martin Bork and his best friend Jens are celebrating with their girlfriends Kalinka and Lotte. The good new? Martin has a job as a night watchman in a morgue. Dinner is interrupted by the grisly announcement that the psychopatic killer, who knifes and scalps prostitutes, has struck again. The next day, the retiring guard greets Martin with “Welcome to Mars!". While showing Martin the ropes the old man recounts the bizarre story of his predecessor - a necrophiliac. In this quietly violent atmosphere the young man starts his shift.
