After being transported away from the Battle of Gettysburg in the previous episode, Tony Newman and Doug Phillips find themselves in the midst of a different battle at their new location/time period. Upon inspecting a nearby shield on the ground, Newman and Phillips ascertain that it is of Chinese origin and they are in the time period of Genghis Khan. They then get captured by men on horseback and are taken into a nearby tent when a man identifies himself as Batu, the grandson of Khan, who believes Newman and Phillips are Marco Polo’s men and they must provide him with information on how to capture Polo’s fort (which they had been unable to do for months).
