Complexo do Alemao, a favela in Rio de Janeiro, has lost generations of young men to gun violence between gangs and police. The film follows residents who believe boxing offers an alternative to that fate, spending time in a local gym where coaches and fighters describe training as a way to keep kids off the street corners where shootings happen. Interviews with families who have buried relatives sit alongside footage of sparring sessions and community life in the favela's narrow alleys and hillside walkways. The gym becomes a stand-in for a larger argument about what discipline and structure can do in a place where the state mostly shows up as armed patrols. Boxers talk about specific fights, specific losses, and specific reasons they chose gloves over guns, grounding the film's larger claim about violence prevention in individual stories rather than statistics. It runs a tight sixteen minutes, focused entirely on this one gym and this one neighborhood rather than the broader politics of Rio's favelas.
