Synopsis by Hal Erickson
On an archeological expedition to the planet P3X 888, Jackson (Michael Shanks) discovers an ancient, primordial Goa'uld symbiote. But before he can return to the complex with this artifact, Jackson is captured by a Unas (Dion Johnstone), a huge, primitive creature. The SG-1 team would like to rescue Jackson, but their efforts are stymied by an unexpected threat. (The name of Jackson's Unas captor will undoubtedly bring a smile to the lips of anyone familiar with the 1970s Saturday-morning adventure series Land of the Lost).
