Prequel to the popular "Dallas" TV series focuses on the origins of the Ewing-Barnes feud during the 1930s. Narrated by Larry Hagman as J.R. Ewing, the film begins at a 1951 barbecue where “Digger” Barnes fires a shot at Jock Ewing, then flashes back to the 1930s. Jock and Digger, initially friends bonded over their ambition to find oil, become rivals as they both vie for the affections of Miss Ellie.

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?

In the second of two Dallas reunion films, War of the Ewings follows Bobby and Sue Ellen Ewing two years after taking over control of Ewing Oil. Although J.R. is managing WestStar Oil, he wants to once again own his father's company. When he discovers that Ray Krebbs' land has undiscovered oil on it, he clashes with everyone — from Carter McKay to the Ewings — to get what he wants.
