A girl with a beautiful voice lives in a little village and dreams of becoming a successful singer. She is discovered by the music maestro Signoretti who tries to have her take part in the music festival of Sanremo, Italy's most famous singing competition.
In Liverpool there's a gang war between the Mods (who dress in the latest fashions and styles) and the Rockers (who are more into the '50s "greaser" look). Ricky, the son of a wealthy businessman, is a Mod guitar player, and in a gang fight with some Rockers, his girlfriend is killed. He leaves Liverpool for the continent and winds up in Rome, where he becomes involved with his father's mistress.
