There is infrequent strong language ('f**k'), as well as milder terms (for example, 'shit', 'bullshit', 'hell', 'God', 'Jesus, 'Christ').

The film contains several prolonged, intense and upsetting scenes containing references to murder and injuries suffered by the school shooter's victims. There are also references to the shooter's deteriorating mental health, including a brief reference to his suicidal ideation, and a scene in which his mother describes his threats to attack her. During some of these scenes, the parents cry whilst recalling past incidents and associated trauma.
