While the Enterprise helps repair Cardassian damages to space station Deep Space Nine, Worf is approached by an alien, who claims his father was not killed in the battle of Khitomer decades ago, but, is still being held in a Romulan prison camp. Initially, Worf rebuffs this, for the dishonor it would bring his family, but changes his mind and resolves himself after talking to Troi and Data. Geordi helps brilliant station scientist, Dr. Julian Bashir conduct an experiment with an unknown alien technology, which causes Data to suffer from a serious accidental plasma shock. As a result of the shock, Data seems to have a vision of his creator, Dr. Noonien Soong, which he is unable to understand. Worf has forced the alien to bring him to the predator-infested forest surrounding the Romulan camp, but, on arrival, he discovers it's not what he expected.
