Pecados de una dama de noche (2014)

An ex-addict call girl, recently released from prison, returns to the same neighborhood that brought her down to search for her missing son. Her ex-pimp uses her desperation to his advantage by selling her services to a local man that has been snooping around in exchange for the safe return of her son. She accepts, but learns the local man is an undercover cop trying to bring down the pimp for his own daughter's death.
