Season 1 Episode 06 - The First Commandment

When SG-9 disappears on a planet, SG-1 is sent to determine their whereabouts. The planet has a high ultraviolet exposure and the team uses heavy sunscreen. When they contact the cave-dwelling inhabitants, they are greeted as gods. SG-1 are quick to correct the local's ignorance, only to find that the SG-9 Leader, Captain Jonas Hanson, is perpetuating the ruse to establish himself as ruler of the planet.

Hanson is forcing the natives to rebuild the Gou'ald temples while condemning any "heretics" to slow death by exposure to the outside UV rays. Jack is ready to fight but Dr. Carter has a previous relationship with Hanson and tries to appeal to his reason. As she tries to renew his feelings towards her, Jack tries to rescue Hanson's surviving squad mate, Conner. Daniel and Teal'c work with Jamala, one of the locals, and first demonstrate where Hanson's "powers" come from, then prepare a demonstration to show the rest of Jamala's people. Once Hanson realizes that Carter is out to sway him, he turns on SG-1 but they prove Hanson is no god and the natives take care of him.
