Boss is an American political drama television serial created by Farhad Safinia. The series stars Kelsey Grammer as Tom Kane, the mayor of Chicago, who has recently been diagnosed with Lewy body dementia, a degenerative neurological disorder. The series was broadcast in the United States on the premium television service Starz and was produced by Category 5 Entertainment, Grammnet Productions and Lionsgate Television. On September 27, 2011, before the series premiered, Starz announced that Boss had been renewed for a second season of ten episodes. The first season premiered on October 21, 2011 and the second season premiered on August 17, 2012. On November 20, 2012, it was announced that Starz had cancelled the show. A film was discussed to finish the show's storylines, but those plans were cancelled after series creator Farhad Safinia declined to move forward with the project. Overview As the series commences we follow Tom Kane, the Mayor of Chicago, who has been diagnosed with dementia with Lewy bodies, a degenerative neurological disorder. Determined to remain in charge, Kane conceals the disease from everyone around him except his own physician, Dr. Ella Harris. Kane's marriage to Meredith is one of convenience. His closest advisors, Kitty O'Neill and Ezra Stone, begin to suspect something is wrong with the Mayor but respect the boundary he has erected that precludes asking such questions, though lapses on Kane's part begin to become apparent to others around him, such as the current Illinois governor McCall "Mac" Cullen and The Sentinels political journalist Sam Miller. Meanwhile, Kane and his team work behind the scenes to groom State Treasurer Ben Zajac to become the next Governor of Illinois.
