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.
