Ken and Sandy suspect that an innocent man, Frank Brown, was convicted of aiding a bank robbery. In fact, they gave testimony which helped convict the man. But, they think the man was framed, and they believe that the main reason for the robbery was to frame the poor man. Ken and Sandy are determined to prove he is innocent.
 
But why was this man framed? He is not rich, but he does have a summer house by Black Lake in Connecticut which at least one person is determined to buy. Why is this property so valuable? Was the bank robbery staged so that Frank Brown would be sent to jail and then be forced to sell his property? In the course of their investigation, Ken and Sandy become aware of an intricate plot involving kidnapping, a shady detective, and a big corporation which will do anything to grab valuable resources.
