When the hostile Tlak'kahn invade Stargate Command to steal a mysterious new lifeform, recently court-martialed Major Gus Bonner must lead a team of young cadets to stop them.
The team must protect the maturing alien crysalis from the Tlak'kahn. But when they discover a world plagued by an unknown disease, Major Bonner refuses to leave.
The team discovers a world populated by flying beings who look like Draga, and may be related to the Ancients. Draga gets to know her people, while her human friends try to fight off a Tlak'kahn invasion.
