Boxeo Constitución shows how young people in a subterranean boxing gym rebel against the social darwinism of the argentinian social crisis. The movie follows two adolescent boxers from the disenfranchised suburbs of Buenos Aires on their path to their debut fights. This first bout will decide whether they can hold their hopes up to escape the lack of perspective in their neighborhoods in order to "be someone" one day. When some of their colleagues form a boxers union, their youthful enthusiasm is confronted with the harsh social reality of their sport.
