Soledad Somellera (Libertad Lamarque), an Argentine maid, secretly marries the son of her employers, Roberto Covarrubias (René Cardona). However, Roberto abandons her soon after to marry a wealthy woman, revealing to Soledad that their wedding was staged and thus not valid. Soledad runs away, pregnant with Roberto's child, although soon after, Roberto's mother locates her and convinces him to give up her daughter so that she can grow up without suffering hardships. Soledad becomes a famous singer, adopting the stage name of Cristina Palermo, while her daughter, Evangelina (Marga López), grows into a spoiled brat who, when she has the opportunity to meet Palermo, treats her with contempt, ignoring that she is his mother.
Soledad was the second film made by Libertad Lamarque in Mexico, after Luis Buñuel's Gran Casino (1946). Several film critics, such as Isaac León Frías, Stuart A. Day, and others, considered the film as a recovery for Lamarque after Gran Casino did not have a favorable reception.[1][2][3]
