En route to a paradise planet, the SG-1 passes through the Stargate--and unexpectedly ends up at Stargate Command. A barrage of curious and contradictory events leads to the realization that each of the SG-1 team members has been given an alien brain implant. As Dr. Frasier (Teryl Rothery) endeavors to remove them, the implants manifest themselves as an odd-looking man named Urgo (Dom DeLuise), who can be seen and heard only by the team members--and who cannot be disposed of without causing the deaths of everyone who has been implanted. Director Peter DeLuise, the son of guest star Dom DeLuise, shows up unbilled in a significant cameo role.
