While the Enterprise heads for Bilana III to participate in the testing of a new propulsion method called the Soliton Wave, Worf receives an unexpected visit from his mother Helena and his son Alexander. The Klingon's surprise turns to shock, however, when Alexander informs Worf that he plans to live on the ship with his father. That night, Worf discusses the situation with Helena. She reveals that Alexander has been misbehaving and is in desperate need of his father's guidance. Reluctantly, Worf agrees to take custody of the child. But when he discovers that the boy is lying and acting up in school, Worf threatens to send his son to a rigorous Klingon school.
