Young Mr. Potts is in deep trouble because his prank on his brother went terribly wrong.
His little brother is in deep trouble after eating a poisonous plant on the holo-deck.
Fortunately they are near a starbase that can mend his little brother quickly.
Unfortunately Data freaks out and steals the enterprise. Data flies her to a planet that registers but one life form that turns out to be, Dr. Noonien Soong (Data's father.)
Turns out Dr. Soong activated a homing beacon that forces his creations to come home - but Data isn't the only Soong Android that comes home to call.
Willy Potts has only 24-36 hours and the crew struggle to regain control of the ship...
Lore and Data are back together and when it is revealed that Dr. Soong wished to give Data basic human Emotions, Lore deviously plots to take the chip for himself.
Lore tricks Dr. Soong and takes Data's emotion chip for himself, somehow making him more evil than he was and when Soong realizes what has happened A struggle ensues, which sadly leads to Dr. Soong’s death. (He was already dying) and Lore stealing.
The Crew of the Enterprise finally figure out a way to get to the surface but it is too. Fortunately Data's memory is restored and after a final moment with Dr. Soong the crew are back on course to save young Willy Potts.
The question remains, can brothers forgive each other.
