SG-1 is in Antarctica, examining the site of Earth's first Stargate. Furthermore, the ship is heading down towards the Pacific Ocean and there doesn't seem to be any way to stop it.

They discover that it belonged to Anubis, and that the consciousness of Thor caused the ship to malfunction. With Jonas Quinn now the fourth member of the team, SG-1's first mission is to investigate a supposedly abandoned Ha'tak vessel orbiting Earth. Back on Earth, the teams plan to use the new X-302 hyperspace fighter to send the Stargate away. Meanwhile, on the outside, Teal'c, Bra'tac and Rya'c break into Anubis' stronghold to stop the weapon. In the aftermath of the failed mission to contact the Asgard, Stargate Command struggle to find a way to shut down the Stargate before the resulting energy build-up destroys Earth. But things take a turn for the worse when the Stargate is left mysteriously open and slowly gathering energy which unless stopped will ultimately result in the destruction of Earth. Jonas Quinn makes himself at home at Stargate Command, while Major Samantha Carter works on the new X-302 hyperspace fighter and Teal'c has an unhappy reunion with Rya'c. Daniel Jackson, Colonel Jack O'Neill is pressured by the Russians to allow a Russian to join SG-1. Chulakian, Goa'uld, Jaffa, People of P2X-374Īs SG-1 struggle to come to terms with the loss of Dr.
