In prehistoric Mongolia lived a couple—Bogdo and Fayau. Their happy life is torn apart when Fayau is abducted by an invading tribe. With the supreme guardian spirit "Red Stag"'s blessing, Bogdo ventures out to the ocean but his journey ends without fulfilling his wish to be reunited with Fayau. The Red Stag, however, promises that the lovers' paths will cross again in time. The strong love between Bogdo and Fayau survives through 10,000 years of human history, as they are reborn into the Age of Discovery and again into today's world.
