When a goa'uld cargo ship is caught entering a neutral zone, it is learned that Carter is the pilot and is taken before the system lords. Then it is soon learned that she is the replicator version and has launched an all out war against the goa'uld. If the goa'uld can't stop the replicators, the replicators will overrun the galaxy in a matter of weeks. Can the people of the Milky Way find a way to stop them or will the galaxy fall to an enemy worse than the goa'uld.
