 On a shakedown cruise of the Prometheus, the ship passes through a gravitational distortion from a collapsing star, causing the hyperdrive regulator to be irreparably damaged. A nearby planet was listed on the cartouche of addresses found in Giza and thus may have a stargate. After a short jump towards the planet, the naquadria reactor overloads and must be jettisoned. SG-1 and the crew of the Prometheus plot a course to a once Goa uld-controlled world and their only chance of getting home.
