Stardate 44085.7: While the Enterprise is hurrying to a starbase to save a young boy's life who was poisoned because of a practical joke by his brother, Data suddenly seizes control of the ship and heads for an unknown planet. Data has unknowingly been called home by his creator, Dr. Noonien Soong. On the planet, Data unexpectedly meets Soong and, also to his surprise, his brother Lore who was left adrift in space almost two years ago. Soong reveals that Lore is actually the first prototype and was deactivated because he turned out unstable. It was Soong's intention to supply Data with an emotion chip, but Lore gets the chip and hurts Soong who dies briefly after. While Lore escapes, the Enterprise continues to the next starbase to save the boy.
