While the war between the Federation and the Dominion continues, Klingon General Martok docks his ship, the Rotarran, to take on reinforcements. Worf is shocked to see that one of the new recruits is his estranged son, Alexander. Worf reveals that he sent Alexander to live with his foster parents on Earth years before, after the boy showed no interest in becoming a warrior. Martok encourages Worf to mend fences with his son, but the attempt soon deteriorates.
