It was the last film in which Pina Pellicer acted and was released after her death one year before on 4 December 1964.
[1] Mario, a law professor at the UNAM, known for his impeccable ethics, professionalism, widower and father of Irma, rejects the constant flirtations that his young student Lidia proposes to him.
At a surprise party that his daughter throws for his birthday, he ends up getting drunk and goes straight to a cabaret where he falls in love with a prostitute named Olga, who is in a “toxic relationship” with her pimp and also drug trafficker, César Domínguez.
On the other hand, her friend Sonia, also a prostitute, lies to a man named Víctor telling him that she is a nurse so that he does not leave her.
Both women develop a love story with their respective lover, while trying to get out of prostitution and crime.
