The Butterfly Effect

In scenes of strong violence, people are strangled and beaten with punches, kicks and improvised weapons; a man is stabbed in the crotch during an attack in a prison cell. In various flashback sequences, a dog is wrestled into a sack and covered with lighter fluid; it's implied the animal was set on fire, though this is not depicted on-screen. There are also visual and verbal references to domestic abuse.

A person suffers from painful blackouts in their memory, resulting in convulsions and bleeding from the nose. People are threatened with weapons in some scenes.

Strong language ('f**k', 'motherf**ker') is used throughout; milder terms include 'bitch', 'dick', 'prick', 'shit', 'ass', 'tits', 'pissed', 'Jesus Christ', 'hell', 'God' and 'damn'.

People have thrusty sex under bed sheets in some scenes. Visual references to sex include sexual moaning, a man leaning between a woman's legs implying oral sex, as well as visual allusions to pornography and sex work. A man offers sexual favours in exchange for loyalty in prison.

Some scenes feature discriminatory terms ('faggot', 'retard', 'kike', 'spic', 'n****r') and behaviour.

A man briefly smokes a bong in one scene; drug paraphernalia is seen in a brothel; there are also verbal references to cocaine misuse.

There are visual allusions and verbal references to child sexual abuse which recur throughout, but these are not graphic. A man is threatened with rape by a prison inmate; there is a scene in which a man gropes a woman while she's serving as a waitress.

Verbal references are made to a person taking their own life; a person interrupts a person's suicide attempt.

A man bleeds from his nose during convulsions in several scenes; there is also blood in the aftermath of violent scenes. The ashes of a dog's burned remains are briefly shown. A teen girl has bruises on her arm implying she's been beaten by her father.

Scenes contain sexualised breast and pubic nudity.

Teenagers misuse dynamite which causes a fatal explosion.

People are bereaved and suffer from mental health difficulties.
