The Destiny has jumped into hyperspace and is now traveling through an inter-galactic void. They've also been unable to locate Eli, Chloe and Scott who have been left behind. Dr. Rush has calculated that based on their current energy consumption, the Destiny has insufficient fuel to reach the next galaxy and they are doomed to die. The engines suddenly fail however and they arrange for an expert, Amanda Perry, to come on board via the communication stones and help them out. Perry and Rush have known each other for many years but as a quadriplegic, is experiencing what life has to offer. On Earth, Camile Wray's consciousness has been transferred to Perry's body and is wheelchair bound.

Rush and Young investigate an abandoned alien craft which is just outside the Destiny. While they do this, the crew onboard the ship find the bridge and discover that Rush is responsible for the countdown clock not activating when the ship emerges from FTL.

Chloe's body is taken over by another consciousness. Meanwhile, Dr. Volker is stricken with a mysterious illness.

Rush slips into a coma in the neural interface chair, and Amanda connects with him in the ship’s matrix, but Ginn informs Eli of a problem with that scenario. Elsewhere, Dr. Rodney McKay’s plan to dial the ninth chevron address hits a snag.
