A young widow and her son are caught in a deadly tug-of-war of intergalactic proportion over top-secret alien biotechnology missing from the military - and the original owners want it back! To escape the painful memories of her loss and avoid her lecherous brother-in-law, widow Gayle Randall moves her son far away from the Utah proving grounds where her test-pilot husband Steve crashed a year ago. Alien biotechnology, critical to the top-secret Diamondhead Project, goes missing after Steve Randall's death. His brother Jack, a military 'lifer' still involved with the project, is recruited by the general in charge to investigate Gayle's possible involvement in the device's disappearance. Still coveting his late brother's wife, Jack bargains to recover the device in exchange for his freedom - and Gayle. Meanwhile, the original owners of the alien device want it back, and they've sent someone to retrieve it by whatever means are required. When Gayle finds out what the device is really capable of doing, will she hand it over? Will she have a choice?
