After a plane crash in the Philippine jungle, two men, one an avaricious killer who has come to the islands to search for a fortune in diamonds, the other an international adventurer, must somehow overcome their vast personal differences and desires to survive in the steamy wilderness.

An angry husband accidentally kills an old man while trying to find out where his wife and her Filipino lover are meeting. Because the old man had been trying to improve labor conditions for Filipino field workers, it is thought that the unsolved murder was politically motivated. This sparks labor riots.
