The Stargate is being shut down by the U.S. government, despite Daniel's warning of an imminent Goa'uld attack on Earth. The SG-1 team, armed to the teeth, defy orders and make an unauthorized trip through the Stargate to what they believe to be the origin of the attack. They find themselves on a Goa'uld Pyramid Ship and discover that Skaara is aboard. Skaara was once the young Abydonian friend to O'Neill, but now is the host body to Klorel, son of Apophis. Is Skaara's human spirit still alive under that fierce exterior or has it been consumed by Klorel? The future of the SG-1 team and of Earth depend on the answer.
