R violence type: blood and graphic.
This film contains many violent moments, including rape scenes, and, although not all of them are graphic, they are all strong on a psychological level, and a fair amount of blood is present.
A sequence taking place in a laboratory shows gross and disturbing imagery, such as body parts (eyes, hands, etc.) placed on a table, and people, including a little girl, kept in shockening conditions.
A young man chops up dead people with an axe. Nothing is shown, but the chopping can be heard. Then, we see the young man with some blood on him, along with the rather bloody axe. Later we see many black trash bags which contain the bodies' pieces.
Two men want to force another man to chop up a dead person with an axe; he refuses to do so and one of the other men threathens to break his arm, unless another character chops up the corpse instead. The man screams in agony while the man is twisting his arm; the other character decides to obey and starts chopping the body with the axe (offscreen).
A man threatens another man with a taser. They fight briefly, and a shot is heard from a real gun; one of the two men is dead.
A woman is about to be raped after she tries to lure a man; he hits her in the face, she falls unconscious, then he proceeds to rape her. The woman becomes conscious again and stabs him in the ear with a pen (no blood).
A young man who is quite out of his mind seems to want to rape another man, but does not actually do it.
A female character is raped more than once throughout the movie: all of these scenes are strong and disturbing, more psychologically than visually. She is treated very roughly in-between rapes, especially when she staggers off and begs another character to help her. As she is roughly pulled away, another man holds back the woman she begged for help to. Both of them scream, beg, and cry. She is struck in the face (usually offscreen) several times when she fights back against rape, ad her nose bleeds badly. We also see that her mouth is bloody and her knees appear scraped and bruised.
A man bound to a wheelchair is tortured to give up an information. They use a knife and seem to intend to tear off the nail of one of his fingers, but then decide to cut the finger itself (graphic). The man screams in pain and a woman begs the men to stop. They start to cut another finger before he tells them the information they want. Later on, one of the men who tortured him wears the man's cut finger on a necklace: it is rotting and black.
A woman starts to menstruate and soakes a couch with her blood.
