Alan Clarke's Scum shows a vicious system and doesn't pull any of the punches â€“ or kicks â€“ so relentlessly deployed in the battles between rivals in the power stakes that incarceration promotes. It's the brutal story of life in a modernâ€“day Borstal. Run by the violence and cruelty of both inmates and officers, the system is a jungle which brutalizes all within its walls. Carlin, who has been transferred from another Borstal for retaliation against violent officers, is thrown into this human quagmire â€“ and what follows is a harsh and bitter battle for survival. He realises that the only way is by beating the system at its own game and eventually erupts as leader of a bloody climatic riot.
