Airdate: June 22, 2007

Summoned by the Asgard, the Odyssey arrives at Orilla where Thor explains that the Asgard race is dying from a rapidly progressing disease. Before they take their own lives, they have turned to their allies from Earth, the Fifth Race to whom they wish to bequeath their legacy, all their technology and their knowledge. As the Asgard install a new power core and extensive upgrades to the Odyssey, suddenly three Ori ships drop out of hyperspace and open fire. With the new Asgard energy weapons, Odyssey is able to destroy one of the Ori ships before escaping into hyperspace, but on Orilla a massive buildup of energy destroys the planet. The Asgard race is gone.

As Odyssey heads home, SG-1 makes the unsettling discovery that their new Asgard upgrades seem to allow the Ori to track them through subspace, and they face an Ori attack each time they emerge from hyperspace. Unwilling to sacrifice the Asgard legacy, Landry and SG-1 beam the crew to safety on P3X-474, then face the Ori in battle. Carter envelopes the Odyssey in a time dilation bubble, and the Ori weapon blast that would destroy the ship is frozen in time. However, despite the time they have bought for themselves, the Asgard technology provides no solution, and no simulation offers a means of escape. As decades pass, the team is trapped in time.

Fifty years have passed aboard the Odyssey, but a risky plan might allow SG-1 to undo the past. To prevent history from repeating, Teal'c volunteers to remain old, shielded within a force field, as Carter deactivates the time dilation field. The ship is struck by the Ori blast and disintegrates as the weapon's energy is channeled to activate a reverse time field. Suddenly, time works backwards to the moment of the initial battle, but this time Odyssey escapes into hyperspace. At the SGC, the team prepares to depart through the gate. Only Teal'c recalls the events of the past 50 years, yet all seem to sense that, despite the manipulation of time, life is too short.
