Attack of the Barbarians - S1.E26

Doug and Tony are captured by the Mongols in 1287, led by Genghis Khan's grandson Baku. Tony is tortured until Doug stages a rescue, where they meet with Marco Polo, who is aiding Kublai Khan. Tony falls in love with Sahib, daughter of Kublai Khan that Polo is aiding and who is kidnapped by Baku. The guys rescue her by using black powder that Polo has discovered in China. When Baku launches an assault on the fort where Polo is staying, the Project staff try and send artillery back to the guys. They thwart an attack on the fort while Tony considers staying with Sahib. In the end she returns to her duty and the two part. Doug provides the necessary ingredient to turn the black powder into gunpowder, while the Project try and send detonator caps to assist them. With the explosives the attack is thwarted and the guys are whisked out. (Copyright 2003 Steve Crow)
