When this show begins, the crew of Voyager finds a robot in space. Torres and Kim try to revive this unit but are frustrated by their lack of progress. Eventually, however, the dogged Torres is able to solve the puzzle and the robot is now 'alive'. She then learns that it was made long ago by an extinct race it refers to as 'the Builders'. And, since it also sees Torres as a new Builder, it decides to kidnap her and make her create a new prototype robot. So, it disables her and transfers to a ship run by other robots like it. When the Captain tries to rescue her, the robot ship easily overpowers Voyager and will destroy the ship unless Torres agrees to work with them. What's next?
As I watched, my oldest daughter looked at the screen and commented about what a crappy looking robot they used in the show. She said he 'looked like someone covered in aluminum foil'! Well, even if this is the case, the Builders might have cared little about aesthetics---so I don't necessarily see this as a flaw in the program.
So is the show any good? Well, the plot is VERY unique and the twist near the end is great. Because of this, I strongly recommend you see it--and mostly because the show is among the best of an otherwise sub-par second season.
