The fire that trapped J.R. Ewing (Larry Hagman), his wife, Sue Ellen (Linda Gray), their son, John Ross (now played by Omri Katz), and J.R.'s half-brother, Ray (Steve Kanaly), in the Southfork mansion at the end of Dallas' sixth season is still raging as season seven begins. Fortunately, J.R. et al. are rescued at the last minute by his younger brother Bobby (Patrick Duffy). And speaking of Bobby, he has been divorced by his wife, Pam (Victoria Principal), who then takes up with Mark Graison (John Beck). Meanwhile, Pam's half-sister, Katherine Wentworth (Morgan Brittany), has set her sights on Bobby, making it clear that if she can't have him, no one will. But Bobby prefers the company of his old flame Jenna Wade, played by Priscilla Presley (in previous episodes, Jenna was portrayed by Morgan Fairchild and Francine Tacker). J.R. encourages Bobby to pursue a relationship with Jenna, if only to strike out at J.R.'s hated rival Cliff Barnes (Ken Kercheval) -- who of course is Pamela's brother. J.R.'s own marriage is on the rocks again, thanks to the arrival of his son John Ross' camp counselor Peter Richards (Christopher Atkins), whose schoolboy crush on Sue Ellen rapidly develops into something far more serious. As J.R. deals with this, he must also reconcile himself to the fact that his mother, Miss Ellie (Barbara Bel Geddes), is dead set on marrying millionaire Clayton Barlow (Howard Keel), the father of Sue Ellen's former (and now missing) lover Dusty Farlow. And in another branch of the Ewing family, J.R.'s half-brother, Ray (Steve Kanaly), disposes of his troublesome cousin Mickey (Timothy Patrick Murphy) -- who the previous season had been canoodling with J.R.'s niece Lucy (Charlene Tilton) -- in a dramatically direct fashion. As the season comes to an end, a double wedding is planned involved Ellie and Clayton and Bobby and Jenna -- but events conspire to keep the couples apart. And in the cliffhanger finale, yet another stalker fires another shot in the office of J.R. Ewing -- but this time it is Bobby who falls wounded to the ground!
