We see a stereotypical looking paedophile (think balding, those 70s glasses and similar clothing), walking away with a little girl whilst holding her hand. We see him again leaning almost cheek to cheek with Danikas daughter and stroking her hair. It's implied she's being groomed online by him pretending to be someone else.
A paedophilic serial killer is at large.
The daughter asks her mother about if she thinks she'll have large breasts when she's older because she's been reading an inappropriate book. It appears she also wrote "f*ck me" all over the inside of the book.
The father comments on how "hot" his 16 year old sons girlfriend is. It's clear she's older than him but they don't confirm her age.
We see the son (minor) shirtless kissing the girl/woman on his bed who is in her skirt and bra.
Nothing that would trigger an epileptic seizure as far as I could tell but there are sudden quick changes in imagery in some scenes due to her visions.
The husband is dismissive of Danikas concerns surrounding her mental health and the children's safety. Not so much gas lighting as appearing fed up of listening to her and trying to shut her down.
A woman's neck is cut by a shard of falling glass. This happens when she chases Danika through a school.
Someone slashes another person's face with a piece of glass from a smashed mirror. It happens after the "victim" punches the mirror.
The only 2 "villains" (other than the white dad who has an affair), are women of colour. 1 is Black (the other person in the affair), and the other is Cuban. They're both involved in inappropriate sexual relationships with Danikas family members.
A third woman of colour is thought to be a "villain" for a second before she explains herself (Filipina lady who is the daughters teacher).
Worth mentioning here that someone cuts their foot on some broken glass on the floor, just in case anyone has a trigger about cut or bleeding feet, etc.
There's a scene where we see a drowned dead dog from under the water of a swimming pool. It's very close up to the submerged side of the dog (he's floating on his side).
Loud noise when Danika comes home and is calling for her family that makes you jump - isn't anything bad though.
A few of her visions could make you jump with the sudden loud noise or visuals.
We see Danika accidentally hit someone with her car. They get up unharmed.
We also learn a child was hit by a car but didn't survive, we see blood and a shoe but we don't see the impact of the body.
We see a lady shoot up heroin. This happens when she crawls into bed with heroin. You'll see her start to tie a rubber band around her arm. Look away until you hear her say something about liking "Kurt".
Not an institution so to speak, but there is 1 brief scene where Danika is speaking to her therapist in a white room with a clock on the wall and a couple of chairs that looks pretty institutional (doesn't have padded walls) but Danika is wearing "normal clothes" and it's clear she hasn't been sectioned.
We see 2 people kissing, the boy shirtless and the woman in her bra on a bed (this is interrupted).
We see a sex scene (we only see a mans buttocks through a semi see through shower curtain and some grunting for less than a minute (this is also interrupted). Non graphic.
