In 1942, war between the Allies and the Japanese rages in the jungles of Singapore. Jim (Khan Chittenden), a Flight Lieutenant in the Royal Australian Air Force, awakens to find himself hanging from a tree by his parachute, shot down in action. Disentangling himself he realises that he has lost his pistol, his only form of defence but manages to salvage his survival gear and sets off into the jungle, narrowly avoiding a Japanese patrol.
Making his way through mud, swamp and a field full of Japanese propaganda leaflets, he eventually runs into Chinese guerrilla fighter Seng (Morning Mo Tzu-Yi) who has also been separated from his unit behind enemy lines. They have another close encounter with a Japanese patrol and elect to set off together to aid each other in reaching friendly territory, despite not being able to speak the other’s language.
Early on in their travels Seng is aggrieved to find the body of a comrade he was close to. They are briefly separated when Jim is left to contemplate the scene but he is alerted to Seng’s location by the sound of gunfire. Jim is forced to rush to Seng’s aid as the guerrilla collapses from a gunshot sustained to the abdomen, the Australian being forced to perform emergency surgery to retrieve the bullet with only bare hands and his sparse survival kit while simultaneously having to keep Seng silent to avoid the attention of the Japanese patrol.
