Bob and Walt Tenor are twin brothers, who not only share a passion for life, but also a liver. Thanks to their teamwork, being conjoined twins is not a handicap to them. But, when Walt's dreams of stardom of acting on the screen and Bob's shyness clashes, they both begin to fall out. This doesn't help when Bob's Internet girl arrives in town, unaware of their handicap, and when Walt gains his own TV show with Cher.
In Martha's Vineyard, Mass., conjoined twins Walt (Greg Kinnear) and Bob Tenor (Matt Damon) make the best of their handicap by being the fastest grill cooks in town. While outgoing Walt hopes to one day become a famous actor, shy Bob prefers to stay out of the spotlight. When a fading Hollywood actress, Cher (Cher), decides to get her show "Honey and the Beaze" cancelled, she hires Walt -- and his brotherly appendage -- as her costars. But their addition surprisingly achieves the opposite.
