After twenty years in prison, the protagonist Juan García García, alias Johnny 100 Pesos, is released and faces a completely unknown and hostile country, where the rules of the game have changed and nothing is what it seems. Now, Johnny, rehabilitated, must use all his wits to prevent his dark past from haunting him. Fate forces him to get involved in a crime to save the people he loves, including a son, whose existence he didn't know existed and who, like him when he was young, is abandoned and alone, and tempted by the paths of evil. Together, they venture through the underworld to the pinnacle of the city's elite, and must overcome obstacles they never imagined in order to survive. On this journey, Johnny will have to confront common criminals and others in white collars, and will experience the love of a woman for the first time.
