With the situation onboard the Destiny dire, General O'Neill and Home World Command orders Col. Young to execute a high risk plan concocted by the I.O.A. scientists which, in theory, could return the crew to earth.

Aboard Destiny, Dr. Rush supervises the exploration of new areas of the ship. Looking for resources to make their everyday lives easier, the crew stumbles upon a piece of Ancient technology that carries the promise of a way home. While somewhat familiar with the find, Dr. Rush can’t guarantee the safety of using it, bringing him and Col. Young to a standoff on what to do.
