In the Sicily of the late 1940s, two brother sculptors, tired of selling madonnas to the local churches, finally realize their dream, and set up a Sicilian production company, thanks to the help of a local bishop. They start producing one box-office failure Z-movie after the other, all with terribly bad local non-pros as actors. Covered in debts, they finally have their great chance, when a local nobleman obsessed by magic decides to invest all his wealth in the making of a movie about Cagliostro, just one year after Orson Welles' Black Magic (1949). They hire a famous American actor (Robert Englund) and start shooting "The Return of Cagliostro".

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.
