Commander Tucker and Lt. Reed have been on a mission to test the targeting scanners on Shuttlepod 1, requiring them to fly the craft at least 20,000 kilometers from Enterprise. During their trials they experienced an unusual jolt that disabled their sensor array and com system, forcing them to return early to the asteroid field where Enterprise has been engaged in a mapping project. Upon arriving at the rendezvous point, the two men are shocked to find a field of debris on an asteroid's surface, including a hull fragment that is unmistakably a piece of Enterprise.
