Having been unjustly court-martialed for defying orders and leading his team into ambush, Major Gus Bonner escapes through the Stargate with a team of young recruits to pursue the hostile Tlak'kahn race which framed him.
Cut off by Nephestis, the team visits a jungle planet where the inhabitants, the Thorn, are dying of a disease Bonner may have accidentally brought to the world on another mission. Meanwhile, the Ancient learns English and acquires a name…Draga.
The team arrives on a planet that has a mysterious "Guide" stone. Gus, Draga, and Seattle get captured and taken through the Stargate along with the Guide. They end up in a trap, and they are stuck. Will Draga use her powers to escape?
Gus and Ec'co go to Ec'co's mother's home planet. Although Ec'co looks like the native people, they consider him as a half-breed alien. While Ec'co proves himself, he and Gus get crucial information about the Tlak'kahn enemy.
When Major Bonner stumbles upon his long-lost mentor, his first impression is that the retired veteran helps the Mustari people prosper. Unfortunately, Major Bonner fails to see the flaws of his old hero.
When Gus and the trainees jump through to a planet almost completely covered with water, Harrison can't resist bragging about his swimming ability.
