Mayor Tom Kane's (Kelsey Grammer) grip on Chicago is as powerful as ever. With high doses of medication, he's able to beat back the physical symptoms of his debilitating brain disease, but it comes at a cost. Committed to his unorthodox agenda, Kane cuts out the cancers within the political machine he helped build. As corrupt heads roll and his list of enemies grows, Kane's virtuous actions begin to erode the very foundation of power he's worked a lifetime to build. In order to maintain it, Kane must govern as he always has - ruthlessly.

Betrayal starts from within. Mayor Tom Kane (Golden Globe winner Kelsey Grammer) is King of Chicago and he rules his domain with an iron fist. Deception, scandal, and betrayal go hand in hand with Kane's form of politics. As long as he gets the job done, the people of Chicago look the other way. Despite being the most effective mayor in recent history, Kane is hiding a dark secret. A degenerative brain disorder is ripping everything away from him and he can't trust his memory, his closest allies, or even himself. Watch as Kane viciously fights battles on all fronts in Boss: Season One.
