Big Sky, Season 1

Private detectives Cassie Dewell and Cody Hoyt join forces with his estranged wife and ex-cop, Jenny Hoyt, to search for two sisters who have been kidnapped by a truck driver on a remote highway in Montana. But 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 killer before another woman is taken.

Forced to form an unlikely team, Cassie and Jenny set out to continue the search for the missing girls. Meanwhile, Danielle, Grace and Jerrie get to work on planning their escape, leading Legarski to struggle with the consequences of his actions as a distracted Ronald deals with a difficult relationship with his mother.

Still on the search for the missing girls, Cassie grows more suspicious of Legarski after a threatening conversation between the two. Meanwhile, Grace manages to make headway on the girls’ quest for freedom. Merilee pleads with Legarski to open up emotionally before it’s too late, and Helen finally confronts Ronald about his increasingly strange behavior.

Unsatisfied with the investigation now that the girls’ disappearance has made headlines, Cassie and Jenny take things into their own hands, tapping into their individual strengths to make headway in the case. Meanwhile, Legarski attempts to keep cool, but Ronald takes a different approach to protecting himself. Still captive, Danielle and Jerrie tend to Grace, who makes a painful decision in an attempt to save them all.

Jenny and Cassie feel as if they’re closing in on Legarski, but they are racing against the clock as he and Ronald are preparing to move the girls. Jerrie makes one last attempt to convince Ronald to let them go. Elsewhere, Cassie visits Merilee to question her about her husband and Ronald aggressively confronts his mother.

After Jenny and Cassie learn the truth about Cody's fate, they decide to officially team up to track down Ronald. Merilee grapples with the fact that she didn't truly know her husband. Helen learns more about her son's recent activities.

The most beautiful places hide the darkest secrets.
