In each episode, which takes place independently of each other, commissioners Jiménez (Luis Luque) and Laurenzi (Darío Grandinetti) must solve different police cases that will be presented to them and will be a challenge for them, for which they will receive the help of the editor literary Daniel Hernández (Nicolás Cabré) who is looking to write a book about crimes.
Two conventional married couples are invited to spend the weekend in the house of their friend Daniel. The meal runs pleasantly until Daniel throws the apple of discord: are you still happy together? Wouldn't you profit from some adventurousness? Did you really choose for this life or was it merely programmed from the start? What's wrong about an open relationship? What follows is a recognizable and amusing discussion where all the layers that characterize the deconstruction of monogamy are expressed: fear and desire, awkwardness and curiosity. The tension becomes explosive when the attractive and provocative Alexandra and Jacobo join the meal and announce their intention to have an orgy all together.
When Roque learns that his ex-girlfriend, Mili, is in a relationship with Cecilia, a woman who severely abuses her, he decides to go and rescue her. Upon arriving at the house, after an argument, Roque fires his gun and ends up killing Cecilia. But when the dead don't rest in peace, it's because they have unfinished business with the living.
