Stargate SG-1: The Sentinel

Stargate Command learns that a planet with a protective shield against the Goa’uld, and once visited by the rouge off world NID team, is now defenseless against an ongoing Goa’uld attack. SG-1 must utilize the service of two of the NID team who visited the planet, who are also currently condemned to a death sentence on Earth, to help save the planet.

However, can SG-1 really trust the rouge NID team members to do the right thing and help them?
