Practice makes perfect, even if you don't practice what you preach. Seems celebrated American marriage counselor Bill Goodman has engineered the ultimate life of double happiness (a.k.a. a lie). The formula? Two wives. Two lives. And his soul mates aren't losers either. Rose is a best-selling romance novelist up in New York, while Charley's a pianist in London, who just so happens has zero tolerance for flying. But Bill's picture-perfect double life gets a double exposure when Rose finds a love letter in his pocket and jets off to London to meet her competition. Together, Rose and Charley work to put a serious dent in his long-term family plans and his frequent-flyer mileage.
