In the third season, private investigator Cassie Dewell (Bunbury), Deputy Sheriff Jenny Hoyt (Winnick) and newly appointed sheriff Beau Arlen (Ackles) use their investigative skills to keep order in Helena, Montana. The trio is faced with a formidable mystery when a local outback trip led by charismatic outfitter Sunny Barnes (McEntire) goes awry. No camper can be trusted and danger lurks around every jagged rock and gnarled tree.
Big Sky's third season, which airs on Wednesday nights, averaged 0.25 in the 18-49 demographic and 2.28 million viewers in the live+same day ratings (including all DVR playback up to 3:00 AM). Compared to season two, that's 18% less in the demo and 12% less viewers. It was one of ABC's lowest-rated scripted series compared to other series on the network.
The series gained 110% viewership in the Live+7 Day ratings, but that wasn't enough to get a renewal for a fourth season.
The thirteen-episode fourth season (the series' shortest season) ended in January.
