Longmire | Netflix

Based on the novels by bestselling author Craig Johnson, the fourth season premiere of Longmire picks up moments after season three’s exciting finale. Walt Longmire (series star Robert Taylor), having found out who was behind the murder of his wife, succumbs to his darker impulses and takes off in pursuit of the killer with murder on his mind. Meanwhile, Branch Connally (Bailey Chase), the deputy who Walt fired for erratic, violent behavior, believes he has already figured out who the real culprit is. But during his confrontation with this suspected killer, a gun goes off. Now the audience will finally learn what happened, and whether Walt can be stopped before he makes a fatal choice. The 10-episode fourth season stars Taylor, along with Katee Sackhoff (Battlestar Galactica, Riddick), Lou Diamond Phillips (Southland, La Bamba), Bailey Chase (Damages), Cassidy Freeman (Smallville) and Adam Bartley (Justified).
