The trick or treaters have come and gone and Kate and Sam are settling in for a quiet Halloween night when a woman appears at the door with a strange request.
Throughout the beginning of the film, a young adult woman is made fun of for "being 22 and still a virgin." Later it's mentioned again that someone nice is around for her so she's not "a virgin anymore." That's the closest it gets in this film - no sexual virgins lose virginity. Especially not on screen
Edge case. A group of young adults spend a long time planning on manipulating a young girl. After they introduce themselves and spend a few hours together, they trick her into thinking they are being murdered. I'm not sure if this could be considered gaslighting as the manipulation isn't long term for the girl
Off camera you hear the dog spite Yelp and you don't see him again. I choose to think he's not dead usually when Sam kills somebody it's far more graphic and painful.
A woman is guilted into having sex with her husband (they end up not having sex but this could still be triggering).
A woman is intoxicated and starts consensually having sexual contact with a masked man. He continues even when she's barely conscious and bleeding.
A woman around 20 something is attacked while walking in the woods by the masked man mentioned above. It's again very clearly sexual for him. Shortly after, she is shown as okay and had beaten him up/fended him off.
53:54 compound fracture shown, doesn't show the bone breaking but shows the aftermath (thigh bone of Steven Wilkins, child killer pretending to be a vampire with a black mask)
a distressed child in a mask on a bus escapes his restraints and accidentally drove it off a cliff in an attempt to go home, it lands in a lake and sinks to the bottom
after the boy with the grocery cart arrives and they go to another house, chip (boy child who is trying to look at the sex) uses it and then the girl in angel mask uses it after him
when the adult child murderer/burier comes back inside his house and calls for his son, his son pops up from behind the kitchen counter with a mask on screaming at the top of his lungs, making the dad also scream
43:25 the mask in the water pops out as a person making the girl in witch hat scream and another person pops out in the background
50:15 older girl in red costume turns around on empty road to vampire man in black mask and screams
when the child in a black witch hat gets in the mechanical lift, after her "friends" scare her by pretending they they were going to kill her, she leaves them behind to be killed by the zombie children from the lake and while she is walking away you can hear excessive audio gore
A man is dressed in a baby outfit but I think that's it. The youngest children you see consistently are about 12. You see a few younger kids about 7 or 8 a few times in the background
Not intentionally. A very buff person in a Viking outfit is seen from behind and looked at in a sexual way because she thinks they are a man. When the person turns around, it's a person with breasts and natural long hair. There is no malice behind all this but it could be triggering
