At the Gates of Hell - Colombia

In the violent streets of Colombia, children left to fend for themselves become hitmen, gang members, or worse. Through their testimonies, this gripping documentary exposes a chilling reality: one of broken childhoods, survival, and redemption in a world where innocence has no place.
