When smokeshow space teens Xena, Sola, and Luna steal Xena's dad's spaceship for an illicit joyride, they run out of gas and come crashing to Earth. There, they meet Dave and Jerry, two equally horny Earth dudes who are good to go and endless scenes of hot, silly, and sultry sex ensue. But when Dave's easy going Uncle Bud is targeted for eviction from his ramshackle beach house, the hormonal honeys must put their libidos aside and enter a bikini contest, the prize money of which will save the day.

The Beach Babes are back... and better than ever! Attempting to return to their home planet, Xena, once again, crash lands the T-Bird ship - this time on a primitive island full of naughty nubile natives. Chased by rampaging dinosaurs and pursued by the evil megalomaniac, James T. Renford II, and his wise-cracking sidekick, Gund, the stranded space sirens have the island rockin'. In an effort to help out the hot heroines, one of the girl's pumped-up playmates rewires Renford's computers which accidentally sets off a chain reaction that will cause the island to explode in an ultimate cosmic climax!
