Spain 1930s. A troupe of performers travel from city to city entertaining audiences and earning a living. The cast includes a magician, a ventriloquist, muscle men, dancers, singers and a full orchestra. The star of the show is Carmen Soler (Trini Alonso) a celebrated singer, now way past her prime, who refuses to retire gracefully and defends her stardom ruthlessly. On her shadow lives and works Ana Marques (Sara Montiel) a younger singer who dreams of the big time and patiently waits for her break.
