There's a long and brutal fight between a man and two other men. The two men attack him at once, and he breaks off and fights one of them. The other one attacks him again, but he breaks the man's neck. The other one stacks him again, smashing many glass panes and hitting him several times. His hand is cut by glass, and it's pretty bloody. He breaks the man's leg, kicks him the groin (his hands get cut with glass bloody), and kicks his head, breaking his neck.
A grenade is thrown into a man's sweater sleeve, and he is shoved into a laundry chute to contain the explosion. His disembodied legs then fall to the floor, his upper torso having been obliterated.
Several fight scenes, nothing too brutal and mostly bloodless. Also a few instances of bloody, but rather stylized, violence.
