What can they do? Shad (Richard Thomas: that’s right, John-Boy of The Waltons) volunteers to recruit mercenaries to help them fight. He fires up an old ship and heads into space, where he meets up with Nanelia, the daughter of an old ally of his people. He also encounters an intergalactic trucker from Earth nicknamed “Space Cowboy” played by George Peppard (The A Team) and Robert Vaughn (The Man from U.N.C.L.E.) as Gelt, who’s on the run and tired of his life as an assassin. A few aliens join the fight; Sybil Danning (in quite the form-fitting costume) as the warrior St. Exmin of the Valkyrie; the group consciousness known as Nestor, and the reptilian Cayman of the Lambda Zone, who has a score to settle with Sador.
Here's a link to an ad for the DVD & Blu-ray release of the film, featuring the original trailer. http://www.youtube.com/watch?v=sySWfZ8oS3Q And remember, like St. Exmin says "Live fast, fight well, and have a beautiful ending."
