Three intergalactic alien beauties—Xena (Sara Bellomo), Luna (Tamara Landry), and Gwen (Nicole Kamien)—accidentally crash-land their spaceship into the ocean off a California beach after stealing their father's starship. Befriended by local surfers and the kindly beach shop owner Uncle Bud (Joe Estevez), the girls learn that Bud is about to lose his business to greedy developer Mr. X (Burt Ward). Utilizing their otherworldly charms and powers, the trio enters a high-stakes swimsuit contest to raise the money needed to save Uncle Bud's shop while enjoying playful, lighthearted romantic flings with the local beachgoers before returning home.
