Dallas: The Complete Twelfth Season (DVD) Season Twelve introduces us to the new Mrs. J.R. Ewing! J.R. has always been a horndog with the Southern Belles, but this season, it all comes back to bite him. A careless dalliance with an Arkansas cutie leads J.R. to the wrong end of a shotgun, 10 years of hard labor, a prison break and ultimately, the altar again. And that’s just the start of another suds-filled season of emotion, promotion and commotion that also includes a tell-all movie (bankrolled by the first Mrs. J.R. Ewing) threatening to unveil every underhanded, low-down trick J.R. ever pulled and a rival oil man scheming to destroy the Ewing empire, taking the clan from Southfork all the way to Austria and Russia!
