There are many scenes of brutality and torture throughout the film, some of which are extremely harrowing to watch.
Near the start of the film a flat full of drug addicts is invaded by a group of man wearing boiler suits armed with bats and machetes. The occupants of the flat are beaten and slashed to death.
Two men invite a male and female to a building complex both the male and female are sexually assaulted and severely beaten with a combination of punches headbuts and kicks.
Two men have a "straightener" (a one on one fight) the fight lasts several minutes and is quite brutal both men use pretty much every part of their bodies to inflict injury on one and other. Fists feet heads teeth elbows knees you name it.
A teenager is tied/nailed to a tree and is beaten to a black and blue bloody pulp by two men with pick axe handles. A third man then shoots him in the head killing him.
