A group of teenage girls heading into the city hook up with a gang of drug-addled ne'er-do-wells and are brutally murdered. The killers find their way to the home of one of their victim's parents, where both father and mother exact a horrible revenge.
This movie contains 49 potentially triggering events.
I don't know what age a certain male character is, so this might not even qualify. He looks to be the same age as the lead teenage character and is treated like a child by his parent. The parent hits him, humiliates him, and forces him to participate in the two worst acts a human can commit.
100% agree with previous comment. The scene is extremely explicit and there is no warning at the beginning of the film so would strongly recommend not watching if you have trauma regarding sexual violence.
Nothing seen anyway but heavily implied, you can see red marks on the high inner thighs of a character when a doctor is looking over them and has a very upset face when seeing their genitalia
There is a part where it seems like a main character has drowned, and there is anpart where someone's face is held under water for a long period of time.
