Colonel Jack O'Neill is pulled out of retirement to head a team called SG-1. SG-1 and over a dozen other teams of military personnel investigate star gates that were discovered on earth and leading to other parts of the galaxy. They will search for alien technology and return with the information to the Star Gate Command based under the Cheyenne Mountain in Colorado. The United States Air Force base hides the top secret command. The SG-1 team runs into the Goa'uld which is an alien race that takes humans as unwilling host bodies. They must fight against the Goa'uld across many galaxies and find out the origin of the star gates that allow such travel.
