Sador of the Malmori and his crew of Mutants roam the galaxy in a huge spaceship armed with a Steller Convertor, the most powerful weapon in the universe. When Sador claims the peaceful farming planet of Akir as a colony, young Shad volunteers to take Sapient Ship Nell and seek out mercenaries who are willing fight him. They find Gelt (a Professional Killer who just wants to live on a planet where no-one's trying to kill him), Space Trucker Cowboy of Earth, Nanelia (a Mad Scientist's Beautiful Daughter), Saint-Exmin of the Valkyrie (a warrior woman looking to prove herself in battle), Nestor (a Hive Mind seeking new experiences) and Caymen of the Lambda Zone, who'd like to settle accounts with Sador for destroying his species. Counting Shad that makes seven. Sound familiar?

After Star Wars became a surprise hit, studios rushed to cash in on the public's sudden hunger for 'Science Fiction' with a flood of bad Space Opera. Exploitation king Roger Corman had no intention of being left behind, but he showed more intelligence than most film executives by ripping off a good plot as well. When SFX companies presented outrageous quotes for their work, Corman took a leaf from George Lucas' book and created his own special effects (under the charge of James Cameron who got his 'big break' with this film, along with producer Gale Anne Hurd, composer James Horner and screenwriter -- later independent filmmaker -- John Sayles). Corman being Corman, he made sure to get his money's worth by recycling the Stock Footage in countless other low-budget sci-fi movies.

Later Caymen cheerfully admits he could sell Nanelia for a good price... but it turns out he's going to sell her as food instead. Tembo and Kalo kidnap a bride and rape her; this backfires badly when they need to concentrate on fleeing from Gelt, and she runs into the control room and starts pushing buttons at random.
