A bomb blows up in Milan and five people die. After only three hours Ravida, the chief of the Secret Service, knows the name of the killer and that of his chief.

Vanessa Gravina is vapidly pretty as the heroine, who changes her hair color and hair style in order to escape an abusive painter husband and start a new life.
