The streets of the world's most notorious slum, Rio de Janeiro's "City of God," are a place where combat photographers fear to tread, police rarely go and residents are lucky if they live to the age of 20. In the midst of the oppressive crime and violence, a frail and scared young boy will grow up to discover that he can view the harsh realities of his surroundings with a different eye: the eye of an artist. In the face of impossible odds, his brave ambition to become a professional photographer becomes a window into his world and, ultimately, his way out.

Growing up in a culture dictated by violence and run by street gangs, teenagers Acerola (Douglas Silva) and Laranjinha (Darlan Cunha) have become close as brothers. With their eighteenth birthdays fast approaching, Laranjinha sets out to find the father he never met, while Acerola struggles to raise his own young son. But when they suddenly find themselves on opposite sides of a gang war, the lifelong friends are forced to confront a shocking secret from their shared past.
