A trio of female cops are on the trail of a serial killer who maybe connected to a satanic cult.

Gabriel, a mentally unstable actor, upon release from asylum falls for aspiring actress Julieta, and tries to help her win film roles – only, she doesn’t fancy him one bit, and merely uses his connections for bettering her career. Her best friend Letícia, also an aspiring actress, uses a friend’s uncle – a senator, to further her ambition. Both their interests clash at some point – crime ensues.

Three stories about three high middle class women from Mexico City who are unfaithful to their partners. 1) Julieta is a married with Eduardo, a publicist addicted to work. 2) Clara is a capricious and fickle girl who is committed to marry Ricardo, a lawyer, until she meets Alfonzo, the architect in charge of remodeling the apartment where the couple will live when they get married. 3) Mariana and Rafaela are married for 10 years and have a daughter, but she is dissatisfied with their marriage until she decides to contact Armando, a man much older than her, through a magazine contact.
