This is a story of a secret organization of former police officers, who go beyond the law, to kill notorious criminals without trial. One police inspector, (Enrico Maria Salerno) tries to stop them, but the attorney (Mario Adorf) is not convinced by his conspiracy theories, so the inspector is basically on his own and can't trust anyone.
Without mentioning the reason, Venetian musician Enrico invites his ex-wife Valeria to visit him, and her heart is broken again during their last days together.
