Dr. Weir is negotiating over the Ancients' outpost with the other Stargate-knowledgeable nations in Antarctica, much to Daniel's dismay. Daniel suggests they contact the Asgard to get them to cure Jack again, using their hyped-up cargo ship but Weir refuses their offer. Sam "persuades" her to let Sam and Teal'c go to the planet of the "evolved" Replicators, which they believe the Asgard should be nearby. Back at SGC, System Lord Camulus makes contact and asks that Earth negotiate a treaty with the System Lords.
Sam and Teal'c arrive but their hyperdrive is burned out and the planet has been replaced by a black hole. They are teleported out just before the ship is sucked in by Thor, who refuses to leave until he completes his mission to determine the Replicators are destroyed. The Asgard engineered the creation of the black hole but the Replicators have formed into a ship and using the time-dilation device, are moving out of the event horizon. They attack Thor's ship and fire a Replicator "missile" into the ship. Going to investigate, Carter is teleporter back to the Replicator ship, which flees. She is confronted by an angry Fifth who tortures her while mind-probing her.
The three System Lords, Camulus, Amaterasu, and Yu, arrive after appropriate precautions are taken. They reveal that Ba'al has gained control of Anubis' super-soldiers – they want the Tauri super-weapon to use against him before he violates the Asgard/Goa'uld treaty and attacks the protected planets. In return they offer hyperdrive engines so earth can create its own fleet. During the negotiations Yu begins to act erratically and Weir bluffs that they already have hyperdrives. The bargaining goes up to the next level when Weir asks for Ba'al's territories in return for destroying him – they consider it but are suspicious, forcing Weir to consider reviving Jack to enable the weapon. A response comes in that Daniel decodes – the System Lords are sending a ship to test Earth's defenses. He shuts down the gate rather then let them leave.
Teal'c and Thor prepare to attack the ship but Replicators aboard the ship delay them long enough for the Replicator ship to reach the new Asgard homeworld, where it is readily blasted apart.
