While Voyager stops for major maintenance on an uninhabited planet, Harry Kim, Seven, and Neelix use the Delta Flyer to search for dilithium when they come across a war between two alien races, the Kraylor and the Annari. After receiving a distress call from a damaged Kraylor ship claiming to be on a humanitarian mission, Harry accepts his first chance at commanding a vessel of his own. However, power goes to his head as captain of the crippled alien ship under attack.
