Using money and intimidation, they succeed in purchasing all the available rubber, but eventually the Japanese commander, Colonel Tomura, gets wind of the scheme. On the last trip to transport the remaining rubber - belonging to part-German plantation owner Bruno Gerber - to a waiting freighter, Carnaghan smells an ambush. He forces Gerber to confess that he tipped off Tomura. Royer decides to try going around the ambush, but Carnaghan refuses to go with him. Royer is killed by the waiting soldiers.
