An alcoholic mafia hit man works to stay sober so he can "go back to work."
Lots of it, ranging from bloody to comic and back. Shooting with handguns and shotguns repeatedly produces bloody corpses (some multi-gun shootouts, some one-on-one battles); Frank's job at a funeral home has him working on corpses daily; ironic "romantic montage" has Frank teach Laurel how to assassinate with a knife (they practice on a watermelon); minor but loud car crash by drunk driver.
Flirting between Laurel and Frank; a woman appears briefly in a bikini; several discussions of Tom's homosexuality and someone's AIDS test; some mild kissing; Frank appears in his underwear.
Multiple uses of "f--k," plus other colorful hitman/gangster language, including "bitch," "s--t," "damn," "a--hole," "douchebag," "dick," "bastard," "c--k," and "c--ksucker."
The protagonist is an alcoholic, so drinking and dealing with it are thematic: He appears dead-drunk at the start, attends AA meetings (which include discussions of other disorders, including eating), relapses (elaborate drinking with a stereotypical group of Irish family members), then recovers. Scenes set in bars. Frequent cigarette smoking.
