A low-rent private investigator and former cop is sent to Austria on a job, and while there sees a number of seemingly unrelated coincidences that lead him into a strange web of corruption and decadence.

Drugs, murders, robberies. In Turin, violence is an everyday fact of life, but a mysterious vigilante starts cleaning up the streets. In fact, the killer is a cop, Moretti, who went undercover to do the dirty work he couldn't do in cop's clothing.

Two police officers attempt to hunt down and arrest a trio of rich kids who rob, assault and kill for fun.

The story is about a youth named Massimo Monaldi, who, living in Rome, is a part-time college student who has some involvement in the protests that occur at his university. Massimo is also involved with drugs and he sometimes steals to make a living and support his habit (the theft of a tobacco box is very important to the story). Among his associates are his girlfriend, Cinzia, who comes from a wealthy family, and he has a wealthy male friend named Rudy who is very naive as well as strangely pampered by his overly-doting mother. Both families don't approve of their relationship with Massimo.
