The base was created on a distant planet to take advantage of a powerful energy supply located there.

Scott and the chief scientist, Dr. Nicholas Rush lead the exploration of the craft. Several areas of the ship have been damaged but it is basically functional. They are able to learn that they are in fact billions of light years from Earth.

A new team is assembled, including some old members, and they go in search of the missing soldier in order to find out how Ra could still be alive. Meanwhile, the alien Goa'uld kidnap Sha're and Skaara, implanting them with symbiotes and making them Goa'uld hosts.
