A thriller based on a true story. Brutal. Honest. Unforgettable.

Medellín, 1989 ? a city where invisible boundaries determine life and death. Carlos grows up in the barrios, where violence is commonplace ? and children learn early on that there are no bystanders: you either become a victim or a perpetrator.

Carlos chooses survival. What begins as protection becomes a downward spiral with no way back. He rises through the ranks of the gangs, becoming part of the underworld ? a feared hitman. Money, power, and fear control his life until he reaches a point where even killing is no longer an option.
