In the pursuit of knowledge, Jack O'Neill, Teal'c, and Daniel Jackson travel to the planet Orban as part of an exchange program. Daniel and Teal'c remain on the planet -- Daniel to study an ancient mosaic pattern on the floor of their Stargate room that he hopes will explain the origin of the Orbanian people, and Teal'c to prepare the Orbanians, should they ever encounter the Goa'uld, by sharing his knowledge with them. O'Neill travels back to Earth with a young Orbanian girl, Merrin, and her chaperone, Kalan, to present the SGC with a valuable Naquadah reactor. All are surprised when it is the young Merrin who volunteers to stay at the SGC and teach Samantha Carter how to build such a complicated technical device. As Carter and O'Neill spend more time with Merrin, they become aware that she is not a typical eleven-year-old. She is incredibly knowledgeable, but has no understanding of fun or play. O'Neill and the rest of SG-1 uncover the truth behind Merrin's intelligence, and how it will affect her and the other children of Orban. He defies orders and sets out to change Merrin's fate by taking her off base, to show her the value of what her childhood could be like and what she has been missing.
