A group of self-absorbed actors set out to make the most expensive war film ever. After ballooning costs force the studio to cancel the movie, the frustrated director refuses to stop shooting, leading his cast into the jungles of Southeast Asia, where they encounter real bad guys.

In Martha's Vineyard, Mass., conjoined twins Walt and Bob Tenor 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, 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.
