The stage is set for retribution as an eclectic group is lured to a secluded European Castle under the guise of a promised "fantasy weekend." And as they read from an obscure storybook, a nefarious tale of avarice is reenacted for their entertainment. However, they are unaware that they have been gathered for their own personal and befitting executions.

The story of Stargate SG-1 begins about a year after the events of the feature film, when the United States government learns that an ancient alien device called the Stargate can access a network of such devices on a multitude of planets. SG-1 is an elite Air Force special operations team, one of more than two dozen teams from Earth who explore the galaxy and defend against alien threats such as the Goa'uld, Replicators, and the Ori.
