Peppino, a slow-witted local villager of the Italian resort town of Amalfi, is bribed to impersonate famed rock and roll star Adriano Celentano for autographs and personal appearances. While Celentano tries to romance Emanuela Mazzolani, the daughter of a well-to-do resident who dissaproves of the union between his daughter and the man he thinks of as a "punk", Peppino, unaware of the true nature of his job to impersonate Celentano, tries to deal with his girlfriend's newborn baby which gets switched around between him and Celentano.

After scoring big in a high-profile bank robbery, a gang of Milanese criminals has to hide in a monastery.

Italian rockstar Geppo has to learn English in order to perform with Barbra Streisand in the US, but falls in love with his beautiful female tutor, Gilda.
