How to Get to Heaven from Belfast: parents' guide

Characters are held at gunpoint, chased, jabbed in the neck with a syringe and hurt in a car crash, with blood and bloody injuries shown. Deaths, including of children, happen offscreen, and a death in the friends' school days drives the plot.

Constant swearing, including f-words and s-words, Irish slang such as "shite" and "arse," and religious exclamations. A song lyric repeats the n-word.

A flirtation between two characters builds to an offscreen sexual encounter, with kissing and references to sex. Some bawdy jokes. No nudity is reported.

Heavy drinking at dinners, parties and clubs: rounds of shots, drunken dancing and hangovers, plus drinking to cope with stress. A fatal accident is blamed on drinking, and several characters smoke. No illegal drugs reported.

A relentless pursuer, a burning building, a wake with a coffin, and the creeping dread of an old secret tied to two girls' abuse and neglect in a religious cult and a fire that killed children. The comic tone softens much of it.
