It's a steamy sex-search as Captain Alexa (Candie Evans) and Lieutenant Raea (Blondi) travel the universe to locate Prince Romash - the last male in a species of Sex Aliens. Following him to a sex clinic on earth, Alexa and Raea send two amorous "probes" (Sheena Horne & Lorrie Lovitt) to sniff out the prince. And what a time these girls have "investigating" the male patients! Even nurse Trina (Tish Ambrose) and Raea are inspired to experience some luscious girl-girl action. Finally, Alexa locates their randy ruler in the form of Dr. Sheen (Ron Jeremy). Watch out! When these erotic extra-terrestrials get together, the action is out of this world!
