Urgo (S03E16)

SG-1 steps through the stargate on its way to a paradise planet and ends up at Stargate Command. Adding to their confusion is Gen. Hammond's assertion that the team was gone for 15 hours, not the mere moment that the SG-1 team-members perceived. Medical officer Dr. Janet Fraiser's examinations of the team-members are inconclusive, but an analysis of the MALP (Mobile Analytic Laboratory Probe) data reveals a brief initial image of an alien lab just before the paradise view. They theorize that the paradise image is a means to lure people to the planet. But for what reason? As they try to figure this out, each member of the team begins to experience intense cravings. Fraiser soon figures out what is causing the cravings: a microscopic implant in each SG-1 member's brain. The team is relieved of duty and isolated until Fraiser can find a way to remove the implants. Soon SG-1 is hearing and seeing the image of a man who identifies himself as Urgo. His presence is generated by the implants in their heads; only SG-1 can see and hear him. Though Urgo claims he only wants to record new experiences, SG-1 begins to suspect he has another, more nefarious purpose. (Metro-Goldwyn-Mayer (MGM))
