Mario Landi

In Venice a detective is on the trail of a killer who commits a double murder (a married couple) then more grisly killings occur. Sex, drugs, gore and perversions are ingredients of this sadistic and sleazy giallo.

Five people receive an anonymous letter revealing a secret of theirs and inviting them to come stay at a mansion that houses a clinic run by a corrupt doctor who experiments on the brain of his comatose son.

A reformed prostitute joins forces with a paid assassin to end an Italian gang war.
