The musical group "Flor de Lis y los Dos del Orinoco" tours the fairs of the towns with their repertoire of old melodies. They arrive in Torremolinos and settle in a camping site. There they meet Johny, a cheeky "go-go boy" who lives off the land and, if possible, from foreigners. He joins them and turns them into a beat band. They dress like hippies and sing in English. Their new stage name is "Los Hippy-Loyas", and they present themselves to the public as a pop group from Liverpool. Their new life leads them to the most unusual adventures.
