Two decades since viewers last saw them, the Ewing's are back. Television's first family of drama, sabotage, secrets and betrayal are gathering at Southfork Ranch for the upcoming wedding of Bobby's adopted son, Christopher, to Rebecca Sutter. Although the occasion is joyous, an old family rivalry crosses generations after secret oil drilling on Southfork results in a major gusher. Everyone has his or her own agenda when the fight over oil and land threatens to tear the Ewings apart once again.

Just as John Ross sets out to claim his birthright and make his father proud, J.R. decides to move back to Southfork, much to Ann's dismay. Bitter Ewing family enemy Cliff Barnes returns and tries to reconnect with his nephew, Christopher. A startling family announcement offers an opportunity to heal old wounds.
