During World War 2 the Chinese Expeditionary Forces carry out a deadly and top secret mission in the jungles of northern Burma.

The Chinese military has received intelligence that points to a plot by the Japanese to deploy poisonous gas to win the war. In an attempt to stop the impending massacre, the government sends a team of well-trained militants led by Zhao Ban Kuo (Sun Yi Zhou) and Liao Yi Fang (Jia Qing) in a deadly mission to cross Nu Jiang and head straight for the enemy camp.—ChineseDrama.Info

Their mission was so top secret, they didn't even know what their true intent was. In 1942, the Chinese government received intelligence that the Japanese may be developing a dangerous biological weapon in a remote part of Burma. The Chinese Expeditionary Force, a secret specialized squad, is dispatched to the remote region to try to stop the Japanese actions. Led by the tough female commander, Liao Yi Fang (Jia Qing), the highly trained soldiers can't seem to get along or give their commander much respect. Joining her on the treacherous mission is Zhao Ban Kuo (Sean Sun), Little Knife (Caesar Li), Cao Quo Jiu (Li Tai), Wang Xi Mao (Yuan Shuai), Big Bull (Jin Jia), Long Hair (Di Jie), Grassy Third (Chen Meng Qi) and the Medic (Song Qing). Together, they must survive the tough crossing of the raging Nujiang River, scale the harsh Savage Mountain and locate the secret Japanese camp. Will they all be able to survive the dangerous mission and accomplish their objective?—Rakuten Viki
