Johnny Mays has the moral conscience of a selfish child in the frame of a plain-clothes cop. The city is his playground, the rest of us his toys. He likes to find out where we work, and where we live, and what will scare us most. And Johnny never had a toy he didn't break.

But Johnny starts a car chase, and he pushes it too far. Soon they're fishing for his body at the foot of a dam, and his partner Nick Frazier has been left behind. They were friends, once, a long time ago. Nick had hoped that he might save Johnny.

Johnny's last words still echo in Nick's mind: "I'm going to remember this," he said, a dark fire in his eyes. "I'm coming back for you."

Then the killings start. Killings of people Johnny didn't like. And Johnny's car is dredged up, empty.
