About Big Sky
Two determined women team up to crack a chilling crime on a lonely stretch of Montana road. Cassie Dewell, a private investigator, partners with ex detective Jenny Hoyt to track down two sisters snatched by a truck driver. As their hunt unfolds, they realize the disappearances ripple through the region far beyond the initial kidnapping. With time running short, the duo must outsmart an elusive killer while weighing the costs of chasing leads that pull them into a web of danger. The case tests their trust in each other and pushes them to operate in a world where every clue could be a turning point. The tone stays grounded and intimate even as the case widens, focusing on human costs and the resolve of those chasing truth.
Big Sky premiered in 2020 on ABC and was created by David E Kelley alongside CJ Box. The series draws on CJ Box's Cassie Dewell novels, grounding its story in real world crime concerns. Its narrative pace matches the wild terrain and keeps tension high throughout.
Awards: The show has not secured major nominations or wins to date. Its strengths lie in character work and suspense rather than formal recognition, with praise often directed at the performances of its lead actors and the tense plotting.
While not a global phenomenon, Big Sky reflects a shift toward procedural thrillers that pair rugged rural atmosphere with tough minded female leads. Its Montana setting adds texture, and the show sparked discussions about missing persons cases in rural communities and the value of vigilant cooperation.
Reception centers on brisk pacing and strong performances, particularly from Katheryn Winnick and Kylie Bunbury. Viewers respond to the alliance between a private investigator and a former cop, and to the show's exploration of trust, resilience, and moral ambiguity in crisis situations. It remains accessible without diluting its grit too.
