La Viuda Negra

August 2017. In a parking lot in Valencia appears the body of a man, stabbed seven times. Everything points to a crime of passion. The homicide group of the city, with a veteran inspector at the head, starts an investigation against the clock that soon leads them to a suspect that no one expected: Maje, the young widow, sweet and serene, who had been married to the victim for less than a year.
