Chris looks at the extremes people will go to in order to protect themselves.In the Philippines that usually involves very sharp knives. The blood flows readily in a fishing village and in the jungle. Also in the Philippines, snipers from the Special Action Force test the powers of amulets, which are worn to protect the wearer. Amulets aren’t necessary for the Masters of the ancient Thai sword-fighting art Krabi Krabong, at which Chris tries his hand in a temple.At the foot of the Himalayas the local Nepalese villagers show him a dance to frighten animals away from their crops. The dance has its roots in stick-fighting techniques, which Chris re-introduces to the villagers.
