*When SG-1 visits P3X-797, they discover a world with a unique rotation that results in a light side and a dark side. In the Land of Light live the Untouched, a people descended from ancient Minoans, but on the dark side are the Touched, violent primitives resembling early man. When members of the SGC, including O'Neill, Carter and even Hammond, begin a startling transformation to the same primitive appearance and behavior, Daniel and Teal'c return to the planet to find a cure for the planet's virus that threatens to spread to Earth. *Source: Back of card
