After living abroad for several years, journalist John Royer returns to the United States just after the U.S. enters World War II. His boast that he could easily smuggle rubber, a key wartime natural resource, out of Malaya has him tasked with doing just that. He manages to get someone from his past, Carnaghan, sprung from Alactraz and together they head off to South East Asia posing as Irishmen. Once there, Carnaghan lines up some of his old cronies and with Royer and a few plantation owners plans to smuggle the rubber out from under the Japanese army's watchful eye.
