Another suspect in the shooting, Cliff Barnes (Ken Kercheval), brother of Bobby's wife, Pam (Victoria Principal), tries to jumpstart his return to Texas politics by making trouble for the Ewings in the Texas legislature. Bobby himself, burned out on the family business, tries his own hand at the state senate, a useful place to be once Jock and Ewing matriarch Miss Ellie (Barbara Bel Geddes), mired in a personal conflict that heads toward divorce, find themselves on opposite sides in a land dispute. Other story threads include a rocky marriage between granddaughter Lucy (Charlene Tilton) and a medical student (Leigh McCloskey), and extramarital distraction for lonely Pam and Sue Ellen. Perhaps the biggest scandal of the season is J.R.'s manipulation of a counterrevolution in the Southeast Asian country where Ewing Oil fields were disastrously nationalized--a crime that could come back to haunt him. --Tom Keogh
