Thirty years after the SGC's first trip through the Stargate, a mysterious creature named Draga is discovered inside an ancient Egyptian mummy. Stargate Command must get her back to her home planet, though she is being pursued by a sinister alien race and bounty hunters from Earth.
Led by a veteran soldier named Gus Bonner, a team of four teenage trainees from Stargate Academy head through the gate each week to explore new worlds and discover new cultures. They are wrongly accused of treason and flee across the universe with Draga.
