A man has a nosebleed while standing out in the snow. We see the blood dripping onto the ground, but it is a fairly small amount. He is seen having a nosebleed again later in the film.
The corpse of a frostbitten man is shown with its eyes missing (it is implied that they were eaten by the crows) and you see two black holes where hie eyes are supposed to be. This is not particularly graphic, but it is still somewhat hard to look at, considering that it is focused on He is naked, but his genital area is covered in snow as he is facing upwards. We see two crows eating what appears to be some part of the man's body on top of a crate. It looks like a finger, or possibly even his penis.
A man's fingers are shown covered in blood after he is working very hard on repairing a motor.
A man hits another man in the head with a boot, knocking him unconscious.
A group of crows are shown eating skin off of a man's dead body. We don't see this explicitly (it's from a distance), but there are lots of gross sound effects.
A doctor in a hospital is shown hanging from the ceiling of the hospital room. It is implied that he had hung himself.
