| Ronald Pergman, a 38-year-old unmarried long-haul trucker, abducts Jerrie, a sex worker he meets at a truck stop. Later, while driving on the highway, he comes across two young sisters, Danielle and Grace Sullivan, and kidnaps them as well after their car breaks down. Danielle's boyfriend Justin contacts his parents, former cops Cody and Jenny Hoyt. Cody, a private detective, reluctantly asks his ex-wife Jenny to assist even though she and his business partner Cassie Dewell despise each other. He also contacts Rick Legarski, a state patrolman who informs him that several other young women have disappeared along the same stretch of highway over the past few years. Danielle and Grace attempt to escape, but Ronald overpowers them and locks them, along with Jerrie, in an old shipping container in a remote location. The next morning, Cody meets up with Rick to begin the investigation and, during their talk, Cody suggests that a long-haul trucker might be behind the disappearances. They plan to go to the church to look for the long-haul trucker but, after they climb into Cody's truck, Rick pulls out a gun and shoots Cody in the head. It is revealed that Rick is Ronald's accomplice. ||||||||

| Cody has gone missing. Rick scolds Ronald for kidnapping Danielle and Grace, as they have families and friends who will look for them (unlike the prostitutes they've been taking). After talking with Rick, Cassie deduces he may be a sociopath who could be involved in the girls' and Cody's disappearances. Grace learns that Jerrie is transgender. The girls decide that Ronald might be a perverted "religious fanatic" and try to manipulate him by singing gospel songs. Ronald appears emotionally moved by their songs and troubled over what he may eventually have to do. Rick orders Ronald to prepare Jerrie for the handoff to the trafficking ring, though still undecided about the other two girls. Ronald takes Jerrie to shower and change. She removes a wig and insists Ronald look at her naked, forcing him to see why the trafficking ring would not want her. Ronald takes her back to the container and tells Rick. Now, none of the captives have any value to them. Unable to sleep that night, Ronald spoons with his mother Helen in her bed. ||||||||

Helen confronts Ronald, saying she can tell he's up to no good. The girls manage to loosen a panel on the container and make a hole that only Grace can fit through. Grace tries to escape through a drainage culvert and Ronald follows her, but the culvert collapses between them and she escapes. She encounters a man fishing in a stream and begs him for help, but Rick appears and shoots the fisherman in the heart with a bow and arrow. She runs and Rick shoots her twice in the leg with the bow, disabling her. He ties her up, removes the arrows, leaving wounds that need disinfecting and stitches, and returns her to the container. As Ronald repairs the loose panel, she screams at him in a rage, saying she will escape again and defeat him. ||||||||

In the container, Grace's wounds have become infected and she has a high fever. She notices maggots on some canned meat the girls opened but did not eat; she asks the others to put the maggots on her wounds, as they are a slight disinfecting treatment. Ronald later disinfects Grace's wounds with hydrogen peroxide. He appears at the shop Rick's wife Merrilee owns, introduces himself as "Mitchell," and invites her to a dance, which she accepts. Jenny goes undercover as a prostitute at a truck stop to try to collect evidence and has an encounter with a trucker that almost escalates. Rick appears at the container and injects Grace's leg with a veterinary antibiotic. Jenny and Cassie track Rick's SUV to the site where the girls are being held.

She and Jenny convince Sheriff Tubb to bring a team of officers to the property, but only Rick is found there, as Ronald has moved the girls to the abandoned All-In truck stop. Tubb is scolded by Rick's MHP boss and prepares to arrest Cassie and Jenny for placing a tracker on a police vehicle. Jenny takes all the blame and only she is jailed. Helen accuses Ronald of being involved in the girls' disappearance, calling out his "perverted" urges. He starts choking her, but stops.

### Controversy

After the pilot aired, members of the Rocky Mountain Tribal Leaders Council, Coushatta Tribe of Louisiana, Global Indigenous Council, Great Plains Tribal Chairmen's Association, and the Union of British Columbia Indian Chiefs (UBCIC), among others, addressed a letter to ABC Entertainment President Karey Burke and series creator David E. Kelley, accusing the show of "at best, cultural insensitivity, and at worst, appropriation" due to being set in an area with a disproportionately high rate of Murdered and Missing Indigenous Women & Girls (MMIWG), yet not having any tribal representation in the show."
