One hundred years in the future, two astronauts are sent to uncover the secrets of a 'duplicate' Earth on the other side of the sun. When they crash land three weeks earlier than they had planned, they must embark on a life-or-death mission to determine whether they have arrived back home or on the strange mirror world.
