Another episode designed to expand the universe of "The Next Generation." The episode begins with a tragic episode where a child has played a practical joke on his brother and put his life in danger. He has to get to a star base to get medical attention. While the Enterprise makes its way to the star base, Data suddenly goes out of control. He jams up all the systems on the Enterprise including creating force fields throughout the ship. He sends that ship at Warp 9 to some unknown destination. The crew can't do a thing and don't even know where they are. The access codes were compromised which puts a damper on almost everything. At some point, the ship comes to a stop and Data beams down to the surface. In a house on an unnamed planet is Data's creator, Dr. Soong (played by Spiner) who is the cause of all this deception. He has decided that before he dies, he will implant a tiny emotion chip in his creation. Unfortunately, who should show up but Data's "brother" Lore. He preceded Data and was a bit of a failure, having actually precipitated the "death" of Soong (or so people thought) by betraying him to the Crystalline entity. The action at the house is wonderfully engaging. Once again, an episode to set up future conflicts, but also to explain the whole story of Data and Lore.
