After leaving Gary for dead, Wick and Billy form an unlikely alliance. Meanwhile, Hap becomes the target of Federal agents, who approach Wick to help them build the case against his father. Also, Billy and Emma make their own play to bring Hap down when they travel to Houston to present their proposal to Hap's ex-wife, Annie. And Carla, dealing with her own suspicions of her husband, masterminds a plan to expose his secret affair that holds devastating consequences for Wick.

With Carla behind bars after taking the fall for the stolen report, Hap is more determined than ever to find the mole at Briggs Oil who put her there. But first, Annie pays Carla an unexpected visit to propose a deal that would give both women what they want. Meanwhile, Jules' brush with death brings both Briggs men rushing to her bedside, providing her with an opportunity to come clean with their secrets.

Briggs Oil is celebrating its 30th Anniversary, and the party must go on, even in the wake of the intensified federal investigation into Hap's business dealings. Suspecting there's an informant in his ranks, Hap clamps down on security and nearly exposes his son, Wick, as the source of the leak. This leads Wick to recruit an unlikely accomplice in his desire to bring down his father.

Christmas is a time for coming together, but for the Lefevers, it's a time of difficult choices. Billy faces an ultimatum to either save his marriage by leaving Rock Springs forever or to stay in the oil game alone while Cody experiences temptation in the form of another man. With the Black Elks land deal slipping away, Annie and Hap consider doing the unthinkable –joining forces to help secure this once-in-a-lifetime oil acquisition. Fearing the fate of his son, AJ enlists Tip to help bring the child to safety.
