Gen. Landry and SG-1 travel on the Odyssey to the new Asgard homeworld, where Thor makes an announcement. The Asgard have been unable to reverse their physical deterioration, and they will all soon die. They have chosen to end their civilization in one stroke, but before they do, they want to pass their entire knowledge base and technology along to Earth, as a way of preserving their legacy. Earth is ready to take its role as the fifth race.
Before the proceedings can finish, Ori warships attack. The Odyssey‘s new weapons are able to destroy one ship as the Asgard homeworld explodes. But every time the ship leaves hyperspace, the Ori are waiting for them. Landry and SG-1 decide to make a final stand and beam the crew to a nearby planet in order to take the stargate home. Before the final shot can destroy the ship, Carter activates a time dilation field that, from their perspective, brings events outside the ship to almost a standstill. She figures that this will buy her time to find a way to save the Odyssey and the Asgard technology, or at least their lives.
The task proves more complicated than expected. Even though she develops a matter converter that keeps them all fed and supplied with oxygen, she can not find a way to ensure their survival. Decades pass. Mitchell begins at impatience and makes his way to stir-crazy. Daniel and Vala begin a relationship after a heated argument breaks down Landry passes away. Finally Carter reveals that she has figured out how to reverse the time field and disengage the Asgard technology that is broadcasting their position to the Ori – but they lack the power to implement it. Mitchell suggests that they harness the power of the Ori blast that has been moving slowly toward them for fifty years, and Carter believes it may work. But one member of SG-1 will have to remain old in order to tell the team what to do, or they will simply repeat their experience over and over again.
