New Order, Part 1

"New Order, Part 1" is the first episode of the eighth season of Stargate SG-1.

Plot
At Stargate Command Dr. Jackson plans to go to Antarctica but then Dr. Weir enters and tells him that the talks stalled again. He gets angry about the situation but because she can't do anything she leaves. She later talks with SG-1 and its members protest that they are not allowed to use the Stargate. She tells them that they can't use it because they want to show their goodwill to the world. Major Carter then proposes using the modified Tel'tak to get to Othala to contact the Asgard, who could help Col. O'Neill. However Weir denies that request since they perhaps need that ship in the future to fend off the Goa'uld and because the engines could burn out on the flight.

Later Carter talks with Weir privately and asks her to reconsider her request but she denies. However when Carter threatens to refuse to work on the modified cargo ship, she gets the allowance. Carter then talks with Teal'c about their flight and when Daniel enters he is informed that he has to stay because if the two fail he would be the only one left to help O'Neill. Some time later Carter and Teal'c fly through hyperspace to Halla and during the flight Carter tries to find out how O'Neill modified the engines but she can't find out how he did it. She then tries to start a conversation with Teal'c but it isn't a long talk.

At SGC Daniel again talks with Weir about the talks between the nations when suddenly the gate is activated. They receive a text message from Camulus, a Goa'uld System Lord who wants to arrange a meeting between Earth and the System Lords. Weir is then authorized by the President to start negotiations and Daniel informs her about the System Lords, their behavior and their representatives, especially Lord Yu.

Meanwhile Carter and Teal'c reach Halla but find that Hala's sun has become a black hole and that their engines have burned out. They are unable to break free from the gravitational forces of the black hole. They try transferring shield power to the engines without effect; the hull breaks apart as they are beamed out by Thor. He informs them that the Asgard collapsed the sun to create a black hole to permanently destroy the Replicators on Hala. They estimated that it would take the human-form Replicators two years to reach the time-dilation device used to trap them, so a more permanent solution was devised. As they talk a large block of Replicators, who have reversed the time-dilation device to speed time and their own evolution, form a ship using the energy and matter from the accretion disk of the black hole and escape just before crossing the event horizon, heading towards Thor's ship. They try to escape but the Replicators fire a Replicator-infested projectile on them and board the ship. While Carter and Teal'c start to destroy the Replicators, Carter is beamed away by the Replicator ship, which then enters hyperspace.

On Earth the representatives, Camulus, Amaterasu, Yu, and his First Prime Oshu arrive. They reveal that since the defeat of Anubis, the System Lords balance of power was destroyed. To avoid open war, they divided his territories among them, but Ba'al found Tartarus, took control of the Kull warriors, and that he plans to attack the worlds protected by the Protected Planets Treaty. They ask if they could use the Ancient weapon against Ba'al. After a break the System Lords offer them hyperspace engines as powerful as a Ha'tak for a fleet of Earth ships to take the fight to Ba'al but Weir declines. Instead she proposes that Earth gets Ba'al's territory after they defeated him but the System Lords decline this offer. Afterwards the Goa'uld contact their allies.

In the Asgard galaxy Thor follows the Replicators, which head towards Orilla, the new Asgard homeworld, and rich with neutronium. It is the key component in Asgard technology, the means for the Replicators to make thousands and construct Human Replicators. Meanwhile on the Replicator ship Carter is confronted by Fifth, who is angry about her since she betrayed him. He then rams his hand in her head and starts to torture her. He does this for some time, so that Carter can feel the pain he felt at her betrayal. But once he sees just how much pain Carter is in, he relents. Meanwhile Thor proposes to self destruct his ship to destroy both ships and Teal'c agrees. However before they reach the Replicators, the ship loses power because of surviving Replicators on the ship. Teal'c destroys them while Thor warns his people. The Asgard then send a fleet to protect Orilla and six O'Neill class battleships destroy the arriving Replicator ship.

On Earth Daniel looks on the message which the System Lords got and before they leave he deactivates the gate. It turns out that the System Lords sent a ship to test Earth's defense and so Weir orders the Goa'uld to be arrested.
