The First Commandment (S01E05)

Col. Jack O'Neill and the SG-1 team are sent through the stargate after SG-9 is declared missing in action. When SG-1 arrives on the planet, they learn that the primitive, cave-dwelling inhabitants greeted SG-9 as gods because they carried guns and used powerful sunscreen, which allowed them to survive the deadly UV rays of the planet's sun. The problem is that SG-9 leader Capt. Jonas Hanson has taken advantage of this opportunity for power. Hanson now rules the planet without mercy, forcing the inhabitants to rebuild the giant Goa'uld temples and condemning disbelievers to death by radiation exposure. It's clear that Hanson must be stopped, but how does one stop a god? Capt. Samantha Carter, who once was romantically involved with Hanson, thinks she can reach him. O'Neill is prepared to fight his way into Hanson's compound to save Conner, one of the surviving SG-9 team members. However, Dr. Daniel Jackson and Teal'c might have the best solution: With the help of Jamala, one of the planet's inhabitants, they set out to show the people of the planet that Hanson's power comes from technology — not divinity.
