A secret agent is sent to find a missing formula, stolen from a scientist by a pig-faced villain, in this fast paced Italian eurospy thriller.

The film is composed of five episodes which depict Italians' love lives in the 1960s.

Young nobleman Mino lives with his mother and Marta, the housekeeper, in an old, decaying castle. He is infantile and morbidly attached to the weird duo; his only hobby is taxidermy. Laura, Mino's fiancee, is met with jealousy and hatred by the two women, and decides to leave the castle; but Marta sabotages her car brakes and she is killed. Mino takes her body back to the castle. Meanwhile, his mother is violently arguing with Marta, who throws her down the stairs and repeatedly bashes her head on the floor. The distraught Mino descends into madness: he picks up a stripper at a nightclub and brings her home, then strangles her while having sex next to Laura's dead body. He does the same with a prostitute. Marta discovers these murders and offers to help dispose of bodies. A year later, Daniela (Laura's twin sister) arrives at the castle...

During a trip to Rome, a debauched Shakespearian actor is tormented by the Italian film industry, fans, the press and the Devil, who appears as a little girl seeking to collect his head.
