After being beaten, robbed, and shanghaied, Bart Maverick sets out to expose a respected member of San Francisco society, and the man responsible for his troubles, as a diamond swindler.
Bret is more than happy to escort a lovely young widow with a large sum of cash to the bank. That is until he learns that the money is counterfeit.
Two men steal a state of the art computer and hold it for $100,000 ransom. A chase from the air in the Highway Patrol's Bell 47 helicopter prevents their get-a-way.
