Married to Sabrina (Linda González) and the father to a baby boy, he also shares his home with his 12-year-old sister Estela (Andrea Vergara). Despite her young age, Estela is in a relationship with 17-year-old soldier Beto (Juan Eduardo Palacios), who steals some cocaine from a drug cartel in a bid to earn enough money to run away with Estela. When the plan goes awry, Heli, his sister and their family are drawn into a spiral of violence and retribution from which they will struggle to escape.
