Mayor Tom Kane sits like a spider at the centre of Chicago's web of power; a web built on a covenant with the people. As long as he gets the job done, they look the other way. Yet despite being the most effective mayor in recent history, a degenerative brain disorder is ripping everything away from him. Kane's wife Meredith knows nothing. Only Emma, Kane's estranged daughter, has a chance of learning his secret. This is going to be the toughest term yet for the Boss.
