The smug Devore fear and persecute telepaths, where passage through their space involves frequent inspections to thwart those harboring them. Voyager's technology successfully shields its telepathic crewmen and refugees (up to a point where further use proves detrimental to their health). Complications arise when the wily Devore Inspector Kashyk visits for a fourth time, though now as a defector requesting asylum. Can Janeway trust him or is it a dangerous game of cat and mouse?
