Two Sicilian shopowners who live in Rome pick up some beatnik hitchhikers and the group gate-crashes their seaside villa. In the meantime the two men's wives smell something fishy going on and go to the villa themselves. To make things worse the place is also invaded by three prison fugitives who terrorize the lot.

Franco e Ciccio commercianti siciliani decidono di passare il weekend nella loro villetta in campagna e dragano due bellone e due capelloni. Le mogli sospettose arrivano con i figli. Vengono sequestrati tutti da alcuni evasi dal carcere.
