The show travels first to India where they encounter martial artists wielding terrifying 6-foot-long (1.8 m) swords, a projectile that can sever the limbs of any enemies, and an ancient Indian booby trap which impales its victims as they sleep. In Egypt, how camels were turned into weapons of war are explored. Finally, through painstaking research, they construct the world's first unmanned weapon that went onto the battlefield over 2000 years ago.
