José Luis is a young man from a modest family of Barcelona and he feels genuine passion for motorcycles. His dream is to buy one of a large cylinder capacity, although his economic situation does not allow him by a long shot. Watching a race in the circuit of Montjuic he meets an elegant Italian woman, manager of a team, who made advances to José Luis. But the boy thinks that accessing her wishes he could get the motorbike of his dreams.
