Frenetic in its pacing and with miniscule character development, this trite slapstick farce stars three Italian comics - Paolo Villaggio, Lino Banfi, and Massimo Boldi as the idiot-nephews of a wealthy invalid (Enrico Maria Salerno). The uncle's plan is to teach the trio how to successfully steal for a living but the plan does not have a chance against their exaggerated ineptitude.
