Limping through the stargate with a dart wound obtained during a skirmish with the primitive natives of P2X-374, Capt. Hagman becomes the ninth recruit to fail to fill the late Dr. Daniel Jackson's shoes. But Gen. Hammond is intent on finding a replacement, even if it means taking Col. Chekov's suggestion that a Russian officer join SG-1.

Col. Jack O'Neill is dead-set against that idea; he's also not too keen on utilizing the talents of Jonas Quinn, the fugitive alien who has helped SG-1 gain invaluable Naquadria technology. Quinn, a gifted scientist with a photographic memory, has already memorized all of Daniel's notes.

Teal'c returns to his planet when he gets the terrible news that his wife, Drey'auc, is dying and that his son, Rya'c, blames him.

Shortly after Teal'c's departure, the SGC gate is dialed from offworld by an unknown party, keeping the wormhole open and preventing anyone from using it. At the same time, the offworlder is transmitting huge amounts of energy through the stargate — a tactic that will eventually overload it and create an explosion that will destroy Earth.

Unable to stop the buildup or contact their offworld allies the Asgard for help, Col. O'Neill and Maj. Samantha Carter attempt an alternative method of interstellar travel in the X-302, the first human-built interstellar spacecraft. But just when they are about to make the leap to hyperspace, they are thrown off-course and then ordered back to base.

With only fifty-something hours before the stargate detonates, the Goa'uld system lord Anubis projects his image through the stargate and threatens ultimate doom to Earth.
