The marquis Galeazzo di Torre Alta is murdered by a mysterious killer who calls himself Diabolicus. His heirs are his three brothers and a sister, but all of them, with the exception of Monsignor Antonino di Torre Alta, are killed by Diabolicus. The police are unable to solve the case, but when Antonino gives his inheritance to Pasquale Bonocore, illegitimate son of his father and Pasquale is in prison and therefore can’t be the killer, all the clues are in the hand of the police.

After their boss’ death, two clerks eagerly await the arrival of the next one, each one of them hoping to become the apple of his eye. They compete in every possible way to impress him, which causes lots of trouble and many misunderstandings.

The film consists of six short stories created by different directors, but all the stories share one thing: a warm irony to current events.
