Stardate 41242.4: An away team investigates Omicron Theta, the planet on which Data was found 26 years ago. The planet's surface is completely devastated for unknown reasons. In an underground lab they find parts for another android built by Noonien Soong, identical to Data. The second android, Lore, is activated. Lore later disables Data and assumes his place. It turns out that Lore once had an alliance with a crystalline entity, which consumed the lives of all 411 colonists on the planet. He lures the entity to the Enterprise, promising more food. Fortunately Wesley is suspicious about Data/Lore's strange behavior. He and his mother reactivate Data and attempt to stop Lore. While Data and Lore are struggling for the control of a phaser, Wesley beams Lore out into space.
