Ewing Oil makes a financial comeback as Bobby and J.R. secure important deals, but J.R. is too overcome with anxiety about B.D. Calhoun to savor the success. Bobby becomes suspicious when J.R. acts overly concerned about Southfork's security system. Cliff reluctantly goes through with Jermey Wendell's plan to undermine Ewing Oil and April Stevens continues her ploy to gain back her five percent of the company. Meanwhile, Donna is unexpectedly rushed to the hospital with excrutiating stomach pains and Sue Ellen has another inauspicious run-in with Peter Duncan.
