Friends Aldo, Giovanni, and Giacomo travel from north to south for Giacomo's wedding: the father of the bride, a tyrannical rich man who is both their boss and father-in-law—since Aldo and Giovanni have also married into the family—has entrusted them with a costly piece of modern art, one that looks just like a rather unremarkable wooden leg.
Con man Aldo breaks out of jail and seizes a car at gunpoint, taking its passengers—bumbling police officer Giacomo and nitpicking civilian Giovanni—hostages. An unlikely friendship blossoms.
Salvo and Valentino are two happy Sicilian friends, who do not want to work, because they know that if they find a permanent job, their girlfriends will ask them to marry them.
