Claudia Carrera wants to be a good cop and a good person. In that order. But these goals seem unattainable because of the grief caused by the murder in Madrid of her partner and lover Tomas. To forget about this, she travels to Valencia, where she has to investigate the strange kidnapping of Lara Valls, the daughter of a wealthy family. Soon she will discover that nothing in this case is what it seems, and little by little she empathizes with Lara: both of them are addicted to literature, the past and suffering. Three drugs that can be lethal.
