Violence and horror
A group of teenagers is hunted by a masked figure after covering up a fatal accident. The film includes intense slasher-style violence, and scenes of blood and injury, with some darkly humorous moments. There are several suspenseful chase scenes, sudden jump scares, and moments of graphic violence, like a character being slashed with a hook or attacked in a confined space. Blood is shown during the attacks, but the focus is more on tension and fear than gore. Strongest scenes include:
- Two characters are shot with a harpoon. The injuries aren’t shown in detail, but one character clearly experiences intense pain and is dragged backward.
- Several characters are stabbed and slashed with a fish-hook. One scene features a close-up of the hook piercing a character’s neck.
- Multiple bloody corpses are shown, including one with its eyeballs removed from the sockets.
Sexual material
There are a few scenes with sexual references and suggestive dialogue. One scene shows a couple kissing and undressing, but no nudity is shown. The sexual content is brief and implied and not detailed. In one scene, a woman asks a man to punish her. He says he needs a minute, which she’s fine with. He steps away and talks to himself, trying to work up the nerve to ‘choke’ her. The scene shows both characters being respectful about consent. Nothing ends up happening, and the moment has some humorous elements.
Offensive language
Offensive language is used by the characters often out of fear or anger, including words like “f**k”, “sh*t” and “c**t”.
Youth Advisory Panel
One member of the Youth Advisory Panel attended the viewing. They said that many of the murders were undetailed and bloodless and did not overall come across as scary. They said the close up of the hook going through the neck was the strongest scene. The request for choking during sex was shown to be something that the character does because of her own issues, and is not presented as a normal thing in sex, but was not sure if a younger teenager would interpret it that way.
