Season four of "Longmire" premiered on September 10, 2015. Though the show previously aired on A&E, that network unexpectedly canceled the program at the end of its third season. Netflix subsequently picked up the show.
Netflix faced fewer concerns than A&E regarding the older age of the typical "Longmire" viewer, and the online streaming service plans to allow the show's producers considerable flexibility in content creation. Season four consists of 10 episodes and stars Robert Taylor, Lou Diamond Phillips and Bailey Chase. Supporting cast members include Katee Sackhoff, Cassidy Freeman and Adam Bartley.The fourth season focuses on the theme of second chances and begins with protagonist Walt Connally's discovery of the identity of his wife's murderer.
