Thor's Chariot (S02E06)

Col. Jack O'Neill and the SG-1 team return to Cimmeria after learning that the Goa'uld have invaded the planet. The team feels responsible because, on their previous visit, they destroyed "Thor's Hammer," the planet's principal instrument of defense against the Goa'uld. The team makes some remarkable discoveries on Cimmeria. Capt. Samantha Carter discovers that she has the power to use the Goa'uld ribbon device. It soon becomes clear that the SG-1 team needs help to fight the massive enemy force led by the vicious Goa'uld system lord Heru-ur. Teal'c, O'Neill and Olaf head out to scout the Goa'uld encampment and soon find themselves face to face with the enemy. Meanwhile, Dr. Daniel Jackson, Carter and Gairwyn journey to the Hall of Thor's Might, where they believe they might find weapons to defeat the Goa'uld. There they are challenged with a series of tests by a hologram of Thor, the Asgard god who guards the planet. Can they pass the tests and find a way to defend the planet? And can they do it before Heru-ur's army wipes out the rest of the Cimmerians and the rest of the SG-1 team? (Metro-Goldwyn-Mayer (MGM))
