Who shot J.R.? One of the men he cheated in business? One of the women he cheated in love? Or is the culprit closer to home: a member of the big, unhappy Ewing family who wanted to reduce the population of Texas by one? Series 4 solves the mystery. But there's still plenty of intrigue and emotional firestorms to come - with a power struggle over Ewing Oil, political scandal, two weddings, two-timing, a dead body in the swimming pool and more Dallas-style fun and games.
