Manolo is a Spanish singer who has fallen in love with a young lady called Eva, it happened as soon as he saw her picture in a calendar. The problem is that Manolo suffers from constant hallucinations and keeps seeing Eva everywhere. He doesn't know that she lives right above his flat and they argue through the window every time Manolo tries to play the piano while writing music because it bothers her badly. Manolo, following his therapist advice, travels to Puerto Rico to perform in a hotel because the pictures for the calendar were taken there.
