SG-1 has changed the course of history and made the SGC virtually non-existent. Doctors Carter and Jackson have helped Brigadier General Hammond to find the Antarctic Stargate, but are not being allowed to help any further. They help Jack to power up the time machine, and he gets Hammond to allow them on the mission to Chulak to find Teal'c.
