Towards the beginning of the film you see a woman in the shower, no nudity, but shower curtain is very thin, get a clear outline of nipples and body from wait up.

A man and a woman talk about a man cheating on his wife with her sister using sexual slang.

Erect nipples are visible through clothing.

A man is seen in another man's bed. (more implied)

A woman shoots a man three times and throws the gun into a thick forest from her car.

Several flashbacks show a woman awakened in bed at night by a man duct-taping her mouth and chloroforming her: she is then shown in a deep hole in the woods, where she removes the duct tape with her teeth and fingers, finds a human shin bone and screams, finds a hairclip attached to a long lock of brown hair, she digs in the dirt and finds jewelry and small pieces of what could be human or animal skin; a man climbs down into the hole and she subdues him with an arm lock and a punch, she climbs out and escapes.

An unconscious woman awakens in the crawlspace under her front porch to find her mouth duct-taped and wrists taped together; we see dirt, cobwebs and spiders as she pulls the tape off with her fingers and teeth, kicks open a thin door that was nailed shut and releases herself; she approaches friends and police officers at her house, cries and shouts for them to find her sister.

Several car chases by police following a woman involve erratic driving, vans and cars nearly hitting one another, screeching tires, sirens, cursing and shouting; there are several stops at houses and businesses where police draw their guns, but do not fire.

A woman pulls a handgun from a dresser drawer and places it in her tote bag; she later points it at men and women she questions about a possible crime.

In a Krav Maga self-defense class, we see women and men attack partners and get punched, pinched, knocked down, arm-locked, pounded hard with fists and eye-gouged (we see some reddened skin on faces and arms); an instructor pulls a woman off a man and tells her to cool down.

A woman in a police station argues with a panel of detectives about her sister's kidnapping and they belittle her; she cries, shouts several times, leaves and when the detectives call her cell phone, she tells them to leave her alone until a serial killer is dead.

Throughout the film, a woman is hyper attentive to her surroundings and wary of being kidnapped a second time (her first time was a horrible ordeal that took place one year earlier).

We hear that a mother died of cancer, that a man and a woman died in a car crash, and that an older woman died, leaving her husband a weird insomniac.

A police supervisor warns his team that a psych patient is on the loose with a gun and could get them sued for wrongful death.

B*tch is used several times.

1 F-word, 5 shit, 4 ass, 3 hell, 1 religious profanity

A woman asks another woman if she needs "ups or downs" to help her study (implying drugs) and the woman says no. This is said jokingly.

A woman takes two pills of medicine at work with soda and throws away three remaining pills.

A woman tells a friend that she is not crazy and that the police want to lock her up and make her take more pills.

We hear that a serial killer drugs college-aged women and abducts them.

We see a close-up of an empty syringe.

We hear several times that a woman is a problem drinker or alcoholic (we do not see her drink alcohol).

Several jump scares through the film.

At many moments in the film when the main character is suspicious of people the tone of the film becomes especially eerie.

A sociopath kidnaps a woman and the movie focuses on trying to identify this person. There are several scenes which depict kidnapping which are intense.

We hear about a kidnapper that tortures and murders his victims.

The "showdown" in the end would be especially frightening for younger viewers.
