Berlinger, a millionaire manufacturer and stolen gem dealer, will be transferring diamond to a Syndicate boss for $75 million. Only one man knows where the diamonds are - Hoffman, Berlinger's former lieutenant, who stole them. Berlinger is torturing Hoffman for their location. The IMF must get the gems and the money. Barney springs Hoffman and they become partners so Hoffman dives for the gems (hidden on the body of a courier sunk at sea). Casey brings Berlinger to Jim, posing as a diver, who offers to get the diamonds. Willy follows Hoffman to the gems and the team knocks him out and takes him into custody - then Jim leads Berlinger to the same spot and offers to make a deal in return for his $5 million payment. Under pressure from the Syndicate, Berlinger agrees and in the subsequent meeting the police capture everyone.
