Big Sky joined ABC’s lineup of pretty well-established shows in 2020 and has carved out its own little niche thus far, as the crime drama is set to return for its second season on network.

The series was created by David E. Kelly, who has history with ABC having created The Practice and Boston Legal, but more recently has been behind some very popular limited series, including Big Little Lies, The Undoing and the just wrapped up Nine Perfect Strangers.

Here is everything that we know about Big Sky and its second season.

What is the plot of ‘Big Sky’?

Big Sky is based on the book series by C.J. Box. In its first season viewers saw private detectives Cassie Dewell and Cody Hoyt team up with Hoyt’s 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. However, they soon discover that these aren’t the only girls that have disappeared in the area. They are in a race against the clock to solve the mystery before another girl is taken.

SPOILER ALERT for anyone not caught up with the events of season 1.

Jenny Hoyt and Dewell, along with Sheriff Tubb and other investigators Jerrie Kennedy and Mark Lindor, discover the identity of the truck driver to be a man named Ronald Pergman. However, they did not learn that he has an accomplice in Scarlett Leyendecker, which allows the two to split up when the team comes to arrest Ronald. While locating the bodies’ of Ronald’s victims, the police transport is attacked by Ronald’s associates in a human trafficking syndicate, allowing Ronald to break free and reunite with Scarlett, while Lindor is involved in the crash and Tubb and Jenny are shot. But Cassie ends up going after Ronald.

That’s a lot going on as season 2 kicks off. Here is the synopsis for the first episode of Big Sky season 2, titled “Wakey, Wakey”:

“Cassie distracts herself with work, while Jenny recovers from her near-death experience, but it won’t be long before a mysterious accident leads them to cross paths. Ronald is wrapped up in something he can’t get out of.”

Who is in the ‘Big Sky’ cast?

Heading into Big Sky season 1, the two most recognizable faces were Ryan Phillippe and John Carroll Lynch. However, (SPOILER), neither actor’s character made it out alive in season 1, though they may return to the series via flashbacks or other narrative techniques on occasion. This opened up the series to be led by the pair of Katheryn Winnick and Kylie Bunbury as Jenny Hoyt and Cassie Dewell, respectively.

Joining the two leading actress as series regulars in season 2 are Janina Gavankar, Brian Geraghty, Dedee Pfeiffer, Omar Metwally and Anja Savcic. Season 1 regular Jesse James Keitel will be a recurring character in season 2.
