Puerto Rican artist Julio Voltio -- a one-time imprisoned gang member -- reconciles with his criminal past in this electrifying concert for prisoners in the notorious, and now-demolished, Puerto Rican prison ‘Oso Blanco’.

This gritty documentary takes you inside the legendary Oso Blanco, the most feared prison of Puerto Rico and one of the most notorious in the Caribbean. It is the birthplace of two of the most dangerous Latino gangs: "Ñeta" and "Los 27" (aka "Los Insectos") and the scene of hundreds of murders.
