Juan Dominguez, while walking the streets of Mexico City, comes across an attractive older woman, Nidia Cachon (Sylvia Pasquel). After flirting with her, they proceed to go back to her house, where she attempts to seduce him. He starts to lose interest when her two daughters, Yadira (Dacia Arcaraz) and Marely (Florencia de Saracho) comes into the house. He instantly falls in love with Marely, quickly losing complete interest in Nilia. Not long after, Nidia's husband comes home.
Nidia approaches her husband and gives him a hug and a kiss, making an excuse as to why Juan is at the house. Her husband quickly dismisses her and calls Juan into his office. All the while a voice over of Juan's thoughts is playing, a running schtick throughout the show.
In his office, the husband quickly explains how his life is not longer worth living. He produces a gun and leaves his family in the care of Juan. He then shoots himself in the head. (Wikipedia)
