 A.J. is transporting $450,000 worth of diamonds by plane for the newly opened Simon & Simon Courier Service when the plane is hijacked and the diamonds are stolen. The Simons become #1 on the FBI s suspect list and to make matters worse there is a ten thousand dollar deductible on their insurance which must be paid before they are paid. The Simons begin tracking down the stolen diamonds while evading FBI agents tailing them. They suspect it might have been an inside job and their investigation leads them back to the airport and Bailey Randall whose company was in charge of the security for the flight.
