The film features very strong language ('c**t') and strong language ('f**k') as well as uses of 'dick', 'piss' and 'crap'. There are also uses of homophobic terms ('faggot' and 'fag') and discriminatory language ('retard'). 
There is a visual BDSM reference when a man is shown gagged and bound by leather, a tray of glasses balancing on his back. A former sex worker asks a man if he wishes to 'f**k' him in the 'ass'. 
Men are shot with, sight of blood spray and bullet wounds on impact. In one scene a man breaks a teenager's fingers, with brief sight of one finger being bent on screen.
In a disturbing scene a grieving man headbutts a mirror during a panic attack. There are also references to a man having been sexually abused as a child.
