Because of the Cats
A thriller written by Hugo Claus, based on a novel by British author Nicolas Freeling.
The search for the culprits in a case of a violent rape takes an Amsterdam police inspector to a nearby garden city where he picks up the trail of a gang of youngsters from rich homes. Divided into gangs the Ravens and the Cats, they take part in violent crimes and strange rites. The inspector manages to disband the gangs and settle the score with the evil, Charles Manson-esque genius behind the scenes.
