Frankenstein Meets the Space Monster

During a solo space mission to Mars, NASA astronaut Col. Frank Saunders (Robert Reilly) who happens to be an experimental android-- is shot down by an alien warship. Frank survives the attack, crash-landing on Puerto Rico. The space aliens led by Princess Marcuzan (Marilyn Hanold) and her putty-eared lieutenant, Dr. Nadir (Lou Cutell) -- decide he must die, so they give chase, but manage to only disfigure him before commencing with their ultimate endeavor: steal bikini-clad young women to re-populate their nuclear-ravaged planet! Meanwhile, scientists Adam Steele (James Karen) and Karen Grant (Nancy Marshall) leisurely tour the scenery on a Vespa motor scooter in search of their creation, Frank, who's busy terrorizing the coastal populace. The marauding aliens crash a swingin' pool party and steal the girls, who are brought aboard their ship to be separated by their lusty attributes and then further frightened by a hairy, skull-faced space monster.
