Cops, crime gangs, and civilians betray each other repeatedly, then seek vengeance in the most violent forms.
Violence is incessant, beginning with cops battling Yakuza members (hand-to-hand fighting and kicking, shooting, stabbing). An early scene shows the brutal murder of Tom's family (frightened wife and child, burning house), which sets up the movie's vengeance theme. Rogue's assaults include throat-cutting, slicing off an ear, shooting, and sticking a sword through a hand. A dog with a bomb on its collar explodes; Jack tortures a suspect by pushing at a bloody wound; a fighting ring shows men slamming against the cage; Kira wields sharp blades; when a man is shot in the head, blood spurts graphically; a father's head appears in a box sent to his daughter.
Bar scenes feature topless, thong-wearing dancers; Chang sends Rogue a prostitute: She strips off her dress and reveals giant breasts and a thong. Cops joke about women on the street being prostitutes (one refers to the other's mother as "working tonight").
Lots of typical action-movie profanity, some of it subtitled, including frequent uses of "f--k," and fewer instances of "s--t," "hell," "damn," "son of a bitch," and "ass." Also a couple of slangy references to genitalia ("pr--k," "p---y").
Mostly expensive cars, including a sleek Spyker C8 Spyder.
Jack smokes several times; his partner notes that it's an "oral fixation" that he should give up. The villain smokes several times as well. Various background characters drink in bars, some "bikers" drink on the sidewalk, and Chang offers Rogue a drink a couple of times, but he refuses.
