When 4 new people come through the stargate, it leads to new opportunities that Stargate Command could never have foreseen.

What will happen when Quinn Mallory, Maximilian Arturo, Rembrandt Brown, and Wade Welles slide into the Gate Room at Stargate Command in July 1998...and find themselves at the center of a secret interstellar war between Earth and the Goa'uld Empire?

The gang is seperated accidentally when their slide is redirected by another artifitial wormhole to a universe where an ancient alien portal has been taken into custody by the US Government.
