A prisoner is delivered unannounced to the prison colony on a world called Necrosis 6 which is illuminated by multiple suns and is thus bathed in perpetual daylight. He is accompanied by a Corvette class female android, who soon demonstrates her skill and speed when it comes to using her two laser sabres. The marshal and his deputies wonder why they were not notified of his arrival and are at a loss to understand why he should have been escorted by such a valuable military asset, who is now forced to wait for the next regular supply ship in order to return to Terra. Meanwhile, the prisoner has undergone the painful process of being fitted with an implant that controls his behavior and which can cause disturbing nightmares and hallucinations, since such devices are of alien origin and were manufactured by a race called the Zek with whom Terrans had fought a devastating war. Our prisoner soon settles in but his true purpose does not become clear until much later when he has gained favor with the prison warden, who wants to make a young girl fall in love with him by having somebody modify her implant. The arid landscape and the settings, as well as the plot, result in this movie resembling a spaghetti movie rather than a tradition sci-fi offering similar to the director's usual output.
