Birmingham, UK, 1919. In the aftermath of WW1, the Shelby family are making a name for themselves as bookmakers, racketeers and gangsters. Nominally the head of the family is the oldest brother, Arthur, but the real brains, ambition and drive in the organisation lies with Tommy, the second oldest. He will carve out an empire for himself that will stretch beyond Birmingham. This with the aid of his family and his gang, the Peaky Blinders.
