Stargate SG-1

SG-1 discovers a planet on which two locals just discovered the Stargate that had been buried for thousands of years. When the team goes through the gate, they meet one of the discoverers, Nyan, an archeologist that was looking for ancient villages. Nyan tells them that the planet is divided into two religions: one that believes that all life began on their planet, and one that believes that the first humans had been brought to the planet using a "gateway." Those two parties have been at war for decades. Unfortunately the Stargate seems to be in territory possessed by the ones that do not believe in the Stargate. Meanwhile the second scientist has warned the authorities and the army comes after the team. Only Teal'c escapes, and he is severely injured. The others are questioned by the army, who thinks they are enemy spies, and don't believe a word of what they say when they explain they came through the Stargate. Now it's up to Teal'c to rescue the rest of SG-1, but while trying to escape he was been shot by a native weapon and loses his eyesight...
