When a police officer is murdered and set on fire, all eyes focus on two other agents; his girlfriend and her lover. Inspired by true events.

It takes us to May 2017. The body of a man appears charred inside a car in the Foix reservoir, in Barcelona. This is Pedro (José Manuel Poga), a police officer. The event quickly arouses the interest of public opinion, and more so as the investigation reveals a network of toxic relationships, deceit, violence and sexual scandals involving Pedro and two of his fellow police officers: his partner Rosa (Úrsula Corberó) and her ex-boyfriend, Albert (Quim Gutiérrez).
