Summoned by the Asgard, SG-1 learns that the Asgard have only a short time left to live. Their final attempt to solve the Asgard's physiological degeneration resulted in each of them developing a rapidly progressing disease leaving them only weeks to live. Fearing their knowledge might fall into the wrong hands they plan to end their lives after handing over their entire knowledge base, technology and history to SG-1. But before all the final advancements can be installed on the Odyssey the Ori drop out of hyperspace and engage the ship. As the Odyssey retreats pursued by one of the Ori ships the Asgard destroy their planet taking the other two Ori ships with them. The Odyssey, with shields nearly failing, is forced to test their new Asgard weapons and is barely able to destroy the Ori ship in time.
The Ori able to constantly track the Odyssey before it has time to repair damage, send ship after ship trying to destroy it. The ability to track the Odyssey seems caused by the Asgard technology integrated into its core systems. The team is caught in a conundrum that the very tools that seemed to promise their victory over the Ori might actually spell their defeat. Beaming the rest of the crew to a safe planet, SG-1 tries to find a way disengage the Asgard technology but are drawn into a fire fight before they have the chance to finish. With shield failed and a final blast just off its hull Lt. Col. Carter (Amanda Tapping) is able to trap the ship inside a time dilation field, slowing the blast to appear itâ€™s nearly frozen moving only inches a year. With a seemingly inexhaustible amount of time Carter sets at solving their dilemma or else the team will be forced to live out the rest of their days in the dilation field aboard the Odyssey.
