Stargate Atlantis: The Rising

The discovery of an ancient secret leads to a shocking revelation that may forever alter the course of history in this imaginative entry from the folks who brought you Stargate SG-1. When the SG-1 crew unearths the remnants of what they believe to be the Lost City of the Ancients -- the very civilization that originated the Stargates -- an investigation by Stargate Command leads a new team of explorers to a distant galaxy. Headed by Dr. Elizabeth Weir, the explorers soon discover the deserted remnants of a highly advanced civilization settled on the ocean floor. When the daring explorers make contact with a group of nomadic humans, the discovery of an otherworldly enemy that feeds on fear offers a grim foreshadowing of things to come for the human race if they don't band together and fight the dark force that threatens to consume them all.
