Detecting the emissions of a matter/antimatter reactor from an uncharted planet in the Gamma Quadrant, Dax and Odo beam down into a village whose simple inhabitants have been disappearing without a trace or any kind of explanation. At first the visitors from the Runabout are prime suspects, but once they prove that they have nothing to do with the series of disappearances, Dax and Odo are entrusted with the task of finding the guilty party. However, someone else in the village already knows the answer to the puzzle - the one person who is guaranteed not to vanish.
