Some prosperous looking gentleman is found with a cracked skull and sustaining a heart attack in Central Park. The position of his underwear indicates he might have been having a recent sexual experience. At first it's assault that George Dzundza and Chris Noth are investigating, but it turns to murder after the victim dies.
It's a torturous investigation, but our detectives uncover a prostitution ring that is run by one upper crust madam played by Patricia Clarkson. And since she caters to the wealthy and mighty a lot of them have a vested interest in seeing she does not go down, at least to the criminal justice system.
Prostitution is the victimless crime some would argue, but Michael Moriarty and Richard Brooks do find some victims and not just of the assault the deceased sustained at the hands of her driver Byron Utley.
Personally I would have taken the slam dunk conviction of Utley who they have dead bang. But that way we couldn't have gotten a story obviously based on the Mayflower Madam.
