Boss (2011)

“Power consumes everyone.”

Mayor Tom Kane sits like a spider at the center of Chicago's web of power; a web built on a covenant with the people. They want to be led, they want disputes settled, jobs dispensed, and loyalties rewarded. If he achieves all this through deception and immorality, so be it. 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. He can't trust his memory, his closest allies, or even himself.
