When new evidence mysteriously surfaces pointing to foul play in Tommy's disappearance, Christopher aims to connect Pamela to the crime. J.R. and John Ross maneuver on two fronts to reclaim their birthright, including poisoning one family member against another. Pamela continues to push her father's agenda to gain control of Ewing Energies. As a new member of the family arrives at Southfork, Ann is pushed to the brink by Ryland's sadistic games and finally takes action.
The battle for Ewing Energies heats up as Christopher and John Ross clash over opposing visions for the company. As Christopher seeks to gain the upper hand in his divorce from Rebecca Sutter, a game-changing revelation turns everything on its head, causing the entire family to put their differences aside and rally together -- except for John Ross, who uses J.R.'s dirty little tricks to take revenge on Christopher and Elena. Meanwhile, Ann is blackmailed by her ex-husband, Harris Ryland, forcing her and Bobby to confront a shocking secret from Ann's past.

With Christopher and Bobby at the helm of Ewing Energies, and Elena working to gain a stronger foothold within the company, J.R. and John Ross strike a deal to wrestle control of Ewing Energies away from them. Meanwhile, Pamela Rebecca Barnes schemes with John Ross to take half of Christopher's shares in Ewing Energies to fulfill her father's desire for revenge against the Ewings. And Ryland's mother, Judith, (guest star Judith Light) proves to be just as evil as her son.
