-->'''Grace:''' With me she let you go. I got the good judgement, you got [[BuxomIsBetter the boobs]].

* ArtisticLicenseGeography: A map shows Helena as being located where Livingston actually is. And with filming [[CaliforniaDoubling taking place in British Colombia]], the setting more closely resembles northwestern Montana, closer to Libby than to Helena.

* ParentalAbandonment: [[spoiler: Ronald kills his mother Helen in a fit of rage. We never hear what became of his father, but he's only mentioned in the past tense, so he might have died.]]

Our story starts with the two young Sullivan sisters, Danielle and Grace, driving through a Montana highway on their way to visit Danielle's boyfriend Justin, when they come across someone nefarious and disappear into thin air. But their disappearance doesn't go unnoticed, and soon they have Justin's private detective father Cody, Justin's ex-cop mother Jenny and Cody's partner Cassie looking for them, with the help of trooper Rick Legarski from the Montana highway patrol. It soon becomes apparent that the sisters are only the latest in a long string of young women disappearing on that county, and the race against the clock is on to find them before they meet a permanent end.

It stars Creator/KylieBunbury, Creator/KatherynWinnick, Creator/RyanPhillippe, Creator/JohnCarrollLynch, Creator/NatalieAlynLind, and others.

** In the Kleinsasser family, the two women are the intelligent and moral ones. Daughter Cheyenne and mother Margaret both loathe their male relatives stupid, immoral acts, trying unsuccessfully to stop it.

* SchoolgirlLesbians: Max and Harper, the two girls among the teenagers who steal the drugs, also have a mutual attraction, sharing a couple kisses (though they don't seem to be formally in a relationship). They know each other from their school.

* DirtyCop: [[spoiler:State trooper Legarski turns out to be involved with sex trafficking, and murders Cody covering it up.]]

* HollywoodLaw: [[spoiler:Legarski]]'s attorney says that positive lie detector test results could be introduced and then help his defense. In fact, American courts don't allow them because of their unproven reliability, which she would know. Also, it's not true that his memory loss in regards to the crimes he's charged with could make him incompetent to stand trial. It relates only to the state of mind during legal proceedings. So long as you still understand and can help your defense, you're legally competent. This may be an InUniverse misunderstanding though, since it's Jenny and Cassie who fear he'll get {{off on a technicality}} due to it, but they aren't lawyers (though as ex-cops in reality they might know this).
* HookerWithAHeartOfGold: Jerrie is a sex worker and a kind-hearted person.
