Traces of the Past (Spanish: Huellas del pasado) is a 1950 Mexican drama film directed by Alfredo B. Crevenna and starring Libertad Lamarque,[1][2] alongside Emilia Guiú, José María Linares-Rivas and Xavier Loyá.

[4] Isabel (Libertad Lamarque) is a woman who left behind her career as a singer to marry lawyer Federico Montero (José María Linares-Rivas).

Years pass, and Isabel, who in the meantime reassumed her career as a singer as "Issa Valetti", upon learning of Federico's death, goes searching for Raúl.

She eventually finds the now grown up Raúl (Xavier Loyá), who now has become a hard-drinking man who hates his mother despite having no memory of her, and is in a relationship with Amanda (Emilia Guiú), a gold-digger.

With Raúl unaware about the relationship he has with Isabel (only knowing her as famous singer Issa Valetti), Isabel tries to change his mind about his mother, but to her dismay, she finds out that Raúl has fallen in love with her "Issa Valetti" persona.
