Private detective Cassie Dewell partners with ex-cop Jenny Hoyt on a search for two sisters who have been kidnapped by a truck driver on a remote highway in Montana. When they discover that these are not the only girls who have disappeared in the area, they must race against the clock to stop the perpetrator before another woman is taken.

"All Kinds of Snakes"

Mark has Cassie meet him at a junkyard where he's found a truck cab. He points out a panel in the sleeper cab that has "help me" and "Kelli" scratched into it. Jenny visits the Lochsa County jail after getting a call from Blake, revealed to be someone she once dated. Blake has been accused of physically assaulting Rosie, daughter of a ranch caretaker who was abruptly fired. Jenny is convinced that Blake, who stood to inherit the ranch, has been set up by the rest of his dysfunctional family, including siblings JW, Rand, and Cheyenne. It soon becomes clear that the Kleinsassers run the county. Jenny takes a back route into the ranch to check out the cabin where Rosie was assaulted and calls Cassie to join her. As Jenny runs into trouble with Rand, Cassie is arrested by a county sheriff and taken aback when the sheriff doesn't stop at the police station. Lindor views surveillance video of Ronald sleeping at his mother's grave. He later leaves a note for Ronald on the headstone. In the present, Ronald enters a remote shack, lighting a candle on a birthday cake that bears the name "Kelli."

"No Better Than Dogs"

While singing at a bar, Jerrie sees Ronald in the crowd watching before he runs off. JW allows Jenny to search the caretaker cabin and she finds a blood-soaked bed with a bottle of whiskey underneath. Cassie is able to call Dewell & Hoyt from the back of the sheriff's car so they can hear her conversation and Mark arrives to use his connections and get Cassie released. Horst announces at a family breakfast that JW will inherit the ranch. Talking to Blake later, Horst hints at people finding out "what's really going on" at the ranch, while Blake brings up a sinister deed from the past. Blake is later shown uncovering the grave of someone named Cole when JW arrives and hits him in the face with the shovel while Cheyenne watches in the distance. Jenny locates a beaten Rosie, who talks about her and Blake being roofied and momentarily waking up to see Rand raping her. While going through Ronald's things, Scarlet finds Mark's note which reads "I am always with you." She confronts Ronald about it, shocking him with his own taser until she is satisfied with his explanation.

"White Lion"

Cheyenne approaches JW to negotiate some demands in exchange for her help in hiding what he has done. Jenny continues to investigate Rosie's assault, but Rosie's own father urges Jenny to back off. Jenny approaches Angela, Sheriff Wagy's receptionist, to see what hold the Kleinsassers have over the police. Though Angela has to clam up when the Sheriff approaches, she slips a note to Jenny agreeing to talk to her later. Scarlet's sister Mary continues to insist that Ronald looks familiar. Ronald later sees a text from Mary on Scarlet's phone stating, "Arthur isn't who he says." After dropping off Scarlet and her daughter, Ronald goes to Mary's house. Cassie and Mark investigate and find a bloody footprint in the house, but no Ronald. They also find a dead body in the basement freezer, but determine it's been there a long time. Angela visits Jenny at her hotel room, but isn't able to say much before they hear a noise outside. Seconds later, a huge truck crashes through the room.

"Nice Animals"

Sheriff Wagy confronts Horst and says he can't protect Rand anymore. Cheyenne surprises Wagy in his vehicle and warns of changes that are coming. Margaret stands up to Horst, boldly stating she plans to kill him, and later tells JW she knows what he did. Ronald takes Scarlett and Phoebe to a camping area in his big rig, selecting a spot that has no cell service. Cassie and Mark comb through Mary's house. Mark says the body in the freezer is a male who disappeared about eight years ago. Jenny visits Cole's mother, who says Cole spoke of learning secrets on the ranch. Jenny and Cassie go back to Gil, who shows them a part of the ranch where Horst has allowed fracking companies to illegally dump toxic waste in exchange for huge cash payments. Horst subsequently paid Wagy to be his eyes and ears. Mark and Jerrie search Scarlet's home and learn from a neighbor that she and Phoebe left with a man in a big rig. Mark shows the man a photo of Ronald and the man confirms it's the guy he saw, but with different hair. Ronald gets caught by Phoebe while burying a body in the woods.

"Bitter Roots"

Ronald convinces Phoebe that he's burying a deer and says they must keep it a secret. Things go from bad to worse for the Kleinsassers. Sheriff Wagy and Deputy Gregor arrive at the ranch to investigate and are met at the entrance by Jenny and Cassie. Gregor tells an angry Cassie he was ordered to kill her, but chose not to. Wagy then says Gregor should have "put her in the ground" like he asked and Jenny records it on her phone, using it as leverage to keep her and Cassie safe. Scarlet gets a call from Lindor, who states that Mary is missing. Scarlet tells Ronald they have to go to Mary's house before the police find something she's hidden. She also admits to knowing Arthur is Ronald Pergman, stating they share a bond greater than love. When they arrive and find the freezer gone, they hear Mark and Jerrie breaking down the door and entering the house.

"Love is a Strange and Dangerous Thing"

Ronald is captured by Mark and Jerrie, but not before telling Scarlet to retrieve the Legarski hard drive he's hidden in her house and call a contact he gives her. When Scarlet does so, she is visited by another Montana Highway Patrol officer who takes the hard drive and drives her away. At the Kleinsasser ranch, Wagy is arrested by state authorities. Margaret and Cheyenne join forces against Horst, later saying they can now run things how they want. In jail, Ronald makes a deal with Mark to give up key players in the trafficking ring and take him to the bodies if Mark takes the death penalty off the table. However, Ronald engineers an escape on the road with two masked gunmen. The second gunman drives Ronald to a site where he is reunited with Scarlet. The two are transferred to another vehicle, where they overtake the driver and take off on their own. Help arrives for a wounded Jenny, who tells Cassie to get Ronald. Cassie retrieves an assault rifle, steals a police car, and drives off in pursuit of him.
