 For years mankind has been visiting other worlds by using an ancient device called a stargate, found in Egypt. Research has shown the stargates have been built by an advanced race called the Ancients. Now another stargate has been found on Earth, in an Ancient base on Antarctica. Scientists think this may have been the lost city of Atlantis and it is found out certain people have an Ancient gene that activates the technology. Dr. Rodney McKay has a different idea. He finds out this particular stargate is able to dial to another galaxy, the Pegasus galaxy, where Atlantis really might be. A team of scientists and military officers decide to explore this location. There s only one problem, powering the device requires a Zero Point Module, currently used for the defense of Earth. There s only one available and returning might not be possible.
