Prequel to the popular "Dallas" TV series focuses on the origins of the Ewing-Barnes feud during the 1930's. Larry Hagman provides the opening narration for the film. The story opens at a 1951 barbecue with "Digger" Barnes firing a shot at "Jock" Ewing. Immediately flashing back to the depression, the two men first meet in a boxcar as both are hoboing. Their original friendship is built on their desires to find oil. But their failings start as they both compete for the hand of the beautiful Miss Ellie. Jock is shown to be an honorable man caught up in a backlash. Digger is a neurotic, alcoholic with a gift for finding oil.

Years after J.R. Ewing lost Ewing Oil and apparently committed suicide, we learn that he is alive and well. He returns to Dallas, and plots what could be his greatest scheme: Bringing his family back together, and regaining control of Ewing Oil from arch-enemy Cliff Barnes. Will he be successful?

It has been two years since Bobby and Sue Ellen Ewing took over control of Ewing Oil. Although J.R. is successfully managing a large oil conglomerate, he wants to once again own his father's company. When he discovers that Ray Krebbs' land, which is heavily mortgaged, has undiscovered oil on it, he knows that if he plays his cards right, he can purchase the land and have enough money to regain control of Ewing Oil. But his business rival Carter McKay also has his eyes on Ray's property, and may soon join Bobby and Sue Ellen as an executive at Ewing Oil. Both parties hatch schemes in order to get what they want.

Seven of the show's original cast members (Patrick Duffy, Linda Gray, Larry Hagman, Steve Kanaly, Ken Kercheval, Victoria Principal and Charlene Tilton) plus guest Mary Crosby, reunited at the real Southfork ranch in Texas to reminisce about the long-running TV show.
