Celda 211

In the 2009 prison film "Cell 211," Luis Tosar stars as Malamadre, the inmate leader of a prison riot, and Alberto Ammann plays Juan Oliver, a young guard who goes undercover as a prisoner to survive the uprising. As the riot unfolds, Juan seeks to maintain channels of communication with the other guards and an incoming GEO team, while Malamadre uses the riot to negotiate with the authorities and exploit the situation for his own purposes.
