The mutilated body of Mayra Cabral de Melo, a well-known stripper, is discovered, and detective Edgar 'Lefty' Mendieta is assigned the case. He has personal reasons for finding the culprit in an investigation that will bring him ever closer to the murderous world of the narcos, who are waging a war against the Mexican state. The country is a powder keg, and Mendieta is about to enter the darkest days of his life. He will need to face not only corrupt politicians, failed boxers, arms dealers, and even the FBI when the father of the President of the United States is attacked, but his own murky past, which just will not leave him alone. As if this was not enough, the reappearance of Samantha Valdes, now the boss of the Cartel del PacLfico, will add yet another piece to this impossible puzzle as Mendieta battles against the odds to bring Mayra's murderer to justice.
