Based on true stories, La Riña highlights the polemic of bare knuckle fights in a playboy party where drugs and drinks are served on silver trays. The party attracts rich people, ex-students from the American school in Sao Paulo, who bet fortunes on poor wrestlers confronting* each other inside an empty swimming pool for a few dollars. A journalist has not been invited, but he manages to sneak into this secret place, using his cell phone to film the guests having fun while watching a deplorable combat. Instead of showing typical poverty in Brazil, La Riña unveils the opposite by unmasking a cruel elite.
