Blanca Lilia Nuñez (
Rosa Carmina) is a successful singer, dancer, and
cabaret star known as "Katya". Unfortunately, she is exploited and manipulated by a gangster nicknamed "El Danzón" (
Miguel Manzano), who pretends to be her representative and makes her an accomplice in all his crimes. Because of this, Blanca Lilia cannot take root anywhere and roams around the world relying on her career as a dancer. Elsewhere, Alfonso (
Fernando Fernández) is a straitlaced teacher of
classical music, who tells off his students if they attend Katya's shows. Alfonso and Blanca Lilia meet in
Cuba. Alfonso immediately feels a strong attraction towards the woman. Their torrid romance in
Havana is interrupted by the intrigues of El Danzón. Blanca Lilia leaves again without saying anything to Alfonso, who ends up returning to Mexico. Back home, Alfonso tries to rebuild his life and marries Ana (Georgina Barragán). Unfortunately, Ana is unable to have children. But Alfonso does not forget Blanca Lilia, and writes a song for her called
Viajera (Voyager). Twelve years later, Blanca Lilia returns to Mexico with her show. Alfonso meets her again: but Blanca Lilia gets involved in El Danzón's theft of an expensive jewel. In the confusion, Blanca Lilia places the jewel in Alfonso's bag, and this jewel accidentally falls into the hands of his wife Ana, who takes it to be an anniversary gift. Both the police and El Danzón are hunting for the jewel and El Danzón ends up attacking Alfonso. During a fight at the nightclub, El Danzón tries to kill Alfonso, and in the end he is himself shot and killed by Blanca Lilia. During the investigation of the crime, the police and Ana finally discover the truth. After a lengthy trial, Blanca Lilia is released. But she does not reveal that she has become pregnant by Alfonso. When Blanca Lilia gives birth to a girl, she decides to visit Ana and hands over the girl, making this sacrifice in the knowledge that she can never be a real mother for the girl now that the shadow of the crime will always remain with her. Alfonso and Ana are reconciled and together they decide to bring up the child, whom they name after her mother. The final destiny of Blanca Lilia is uncertain. ==Cast==
