For J.R. Ewing, Season 13 is as unlucky as a steer at a Texas barbecue. He starts by lying and cheating Ewing Oil to the brink of destruction and ends by kicking and screaming in a psychiatric hospital. In between he tires of his pretty young wife, seethes while Cliff Barnes's political star rises and bumps into a past he didn't know he had. Meanwhile, Clayton and Miss Ellie investigate a multiple-murder mystery, folks from seasons past unexpectedly return to stir up trouble and Bobby stays busy removing J.R.'s knives from his back, chasing after a Pam look-alike, and bringing a new Mrs. Ewing to Southfork. Y'all come 'round and meet the happy couple!
