King Kong

In 1976, Fred Wilson, an executive of the Petrox Oil Company, forms an expedition based on infrared imagery which reveals a previously undiscovered Indian Ocean island hidden by a permanent cloud bank. Wilson believes that the island holds vast untapped deposits of oil, a potential fortune which he is determined to secure for Petrox. Unknown to Wilson or the crew, Jack Prescott, a primate paleontologist who wants to see the island for himself, has stowed away on the expedition's vessel. Prescott reveals himself when he warns the crew that the cloud bank may be caused by some unknown, and potentially dangerous, phenomenon.
