New Ground (S03E19)

The SG-1 team travels to the planet Bedrosia, where, unknown to them, the planet's two cultures have been at war over their opposed beliefs regarding the stargate. Upon their arrival, SG-1 is met by the curious Nyan, a scientist. Nyan explains to them that their arrival through the stargate proves that the beliefs of his rival culture, the Optricians, are true and that humans were brought to this planet by aliens through a gateway. His culture, the Bedrosians, believe that human life evolved without a gateway and was created by their god, Nefertum. The team's arrival is soon detected by a group of Bedrosian soldiers and their leader, Rigar. Col. Jack O'Neill, Maj. Samantha Carter and Dr. Daniel Jackson are captured, while Teal'c and Nyan narrowly escape. During his escape, Teal'c is blinded. Rigar cages his three prisoners and interrogates them as to how they arrived on his planet. He believes that they are Optrician spies; they insist that they traveled here via the stargate. Rather than face the possibility that his people's entire belief system is wrong, Rigar chooses to destroy all evidence, including the SG-1 team. Though blinded, Teal'c, with Nyan's help, must outwit the Bedrosians before Rigar can execute his plan — and Teal'c's comrades. (Metro-Goldwyn-Mayer (MGM))
