In this sudsy made-for-TV installment of the Ewing saga, wily J.R. (Larry Hagman) finds himself discontent merely managing an oil conglomerate and decides to try to regain control of his father's company from Bobby (Patrick Duffy) and Sue Ellen (Linda Gray). But first he needs money. Opportunity knocks when he discovers that Ray Krebbs (Steve Kanaly) has a large untapped supply of oil upon his land. Best of all, Krebbs is ignorant of this fact. Unfortunately, J.R.'s long-time rival Carter McKay (George Kennedy) also knows about the oil and is not about to let J.R. get it.
