Plot Summary

In August 2006, two college students, Olivia Heath and her best friend, Laura, are driving a rural highway to a bonfire. Olivia, who is anxious and follows true-crime blogs, grows unnerved by a truck tailgating their old Volvo. She memorizes the license plate, 2C GR275, and texts it to Laura’s sister, Tish, who is studying at the library. Laura tries to reassure her, and they discuss Tish’s recent, abrupt breakup with her fiancé, Tony, a member of the Delta fraternity. The conversation turns to Ava Robles, a freshman who vanished three years earlier from a party near the reservoir, now nicknamed “Coffin Creek.”

The same truck reappears and begins to menace them on the isolated road. It pulls alongside them, revealing two men in dark hoodies who conceal their faces. The truck then speeds ahead and blocks the road, forcing Laura to stop. The two men, now wearing grotesque red and white latex masks, exit their truck and approach the Volvo. Olivia and Laura attempt to turn around, but the car stalls. The man in the red mask reaches through Olivia’s permanently open passenger window, grabs her by the hair, and tries to pull her out. While Laura restarts the car, the man smashes the windshield with a rock. Olivia fends him off with a boombox, and Laura speeds away, initiating a chase. The truck pursues them, repeatedly ramming the Volvo. The women try to signal an oncoming driver for help, but he misinterprets their panic and drives on. The truck then nudges the Volvo off the road, sending it careening down a steep hillside with Laura and Olivia inside.

The Volvo crashes at the bottom of the valley. The airbags deploy, and Laura, who had unbuckled her seatbelt, is knocked unconscious, suffering a severe concussion and a broken arm. The car comes to rest near a river. As Olivia assesses the situation, a woozy Lauren regains consciousness. After hearing the men approaching from the road above, the women realize they are being hunted. They abandon the car and hide near the riverbank, where they overhear the men confirm the license plate was fake. Both Olivia and Laura recognize one of the voices. To evade the men, Olivia and Laura cross the cold, rocky river. When Laura falls asleep, Olivia climbs back up the hill to find an area with cell service, but she is forced to turn back when Laura wakes up and screams in panic. Drawn by the noise, the men find them. Although Olivia initially runs, she is overwhelmed by guilt and returns to help Laura. From a hiding spot, she watches the more aggressive of the men, whom his friend calls Kyle, unmask himself as he and his friend tie Laura up. Olivia overhears them say “Semper unum,” a Delta fraternity motto, and she makes a split-second decision to hide in the open bed of their truck.

Olivia endures a difficult journey to a remote cabin at 67 Deer Flat. She finds a tire iron in the truck bed and arms herself. Once they arrive, she slips out and hides underneath the vehicle. She overhears Kyle’s friend, who is unnerved by the escalating violence, say that their original plan was only to scare Tish. While Kyle goes inside the cabin, his friend carries Laura from the truck. Olivia emerges and strikes Laura’s captor on the head with the tire iron, knocking him out. The unconscious man is Tony, Tish’s ex-boyfriend. Oliva and Laura try to escape but are trapped by a tall, barbed-wire fence. When Kyle threatens to shoot them, the women surrender themselves. Kyle then reveals that his “gun” is a lighter.

Inside the cabin, Kyle explains that the Delta fraternity runs a human trafficking scheme in which members sexually exploit their girlfriends at parties. Unbeknownst to Tish, Tony arranged for her to be marked with a “red X,” meaning “anything goes.” She became pregnant, and after pretending to have an abortion, she secretly decided to keep the baby, a development that threatened to compromise the entire operation. Kyle and Tony had intended to abduct Tish that night to “take care” of the problem.

Now, Kyle forces Olivia into a foul-smelling crawl space beneath the cabin. Laura attacks Kyle with a small fireplace shovel but is overpowered and thrown into the crawl space with Olivia. Laura breaks her arm in the fall, and Olivia badly sprains her ankle. While trapped, they discover the skeletal remains of Ava Robles, her body marked with a spray-painted red X. Laura correctly intuits that Tony does not know that Ava’s body is there; she believes they can use this information to turn him against Kyle. When Kyle returns, they scream about Ava’s body. A disturbed Tony enters the crawl space to see for himself. Kyle prepares to shoot Tony to silence him, but Tony fools Kyle by pretending to be unbothered and by suggesting that they use the women for target practice.

Back upstairs, Olivia’s nearly dead cell phone gets a flicker of service. She sends a text asking Tish to call the police. The message includes the cabin’s address and the names of their captors. The message is delivered just as the phone battery dies. Kyle and Tony spray paint each woman with a glowing letter X and march them outside to a shooting range. As Kyle prepares to shoot, Tony turns the gun on Kyle and kills him. Tony claims that he killed Kyle to save Olivia and Laura. He expects them to tell the police a cover story that exonerates him of any involvement in the kidnapping and the Delta scheme.

Back in the cabin, Tony discovers that the truck keys are missing. Believing that the keys are on Kyle’s body, he prepares to force the women outside with him. However, Laura panics Tony by faking a seizure, and he leaves them inside alone. While he is outside, Laura reveals that the keys are in Kyle’s hoodie on the floor. Retrieving the keys, they escape to the truck, but Tony sees them and opens fire. Just as he is about to shoot them through the windshield, a police car arrives with Tish in the passenger seat. Tish had received the texts and convinced an officer to drive her out to search, receiving the final address text while out searching. Tony surrenders.

In the aftermath, the investigation exposes the Delta fraternity’s trafficking ring. Eleven members, including Tony, are imprisoned. For his role in the kidnapping, attempted murders, and human trafficking, Tony receives a life sentence; the charge of being an accomplice in Ava’s death does not stick. Ava is given a proper burial. Olivia, Laura, and Tish refuse to participate in the media frenzy surrounding the case and move to a new apartment to heal. Tish decides to keep her baby; a girl she names Chloe.
