When Flinx, no stranger to galactic intrigue, found an unconscious woman on a riverbank deep in the jungles of Alaspin, he took it in stride. When he learned that the woman, Clarity Held, was a brilliant scientist abducted from a remote outpost on inhospitable Longtunnel by a group of fanatic assassins, he tried to help the beautiful Clarity back to her project. Unfortunately, the assassins were still at work. They would do anything to stop the research on Longtunnel and would kill anyone or anything that got in their way.
