Oliver Platt is defrauding his firm Bulmont Investments, not just out of greed but revenge as his father killed himself when a similar firm, for whom he worked, would not give him a loan to pay off his debts. Alan Corwin, an auditor, tumbles to Oliver's deception and demands a quarter of a million in hush money. Oliver puts the money in a brief-case along with a bomb, due to go off at six o'clock when Corwin will be in an aeroplane. Unfortunately for Oliver, his devoted secretary Leila cannot stand by and see her man beaten so she takes action. . .
