A firearm has one power: to fire a bullet that can kill a human being. Brazil is the country with the most deaths from firearms in the world. With this power in hand and these bodies in the account, the documentary points a camera at an ordinary citizen and follows him in the process of acquiring weapons in a country in a trance, undoing the Disarmament Law. With interviews with those who analyze the purchase of weapons in the violence escalation, this film shows the effective need to discuss how a shot in the dark can decide the life and death of thousands of Brazilians.
