As the war between the vampires and the Lycans rages on, Selene, a former member of the Death Dealers (an elite vampire special forces unit that hunts werewolves), and Michael, the werewolf hybrid, work together in an effort to unlock the secrets of their respective bloodlines.

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.
