Gullible Jeannie (Barbara Eden) is delighted when her duplicitous lookalike sister Jeannie II (also Barbara Eden) offers to help Jeannie land Tony (Larry Hagman) as a husband. Of course, Jeannie II really wants Tony all to herself, and she'll stop at nothing to achieve this goal. And as usual, feckless Roger (Bill Daily) is trapped in the middle of all this intrigue. ~ Hal Erickson, Rovi
