"Peaky Blinders" is a gangster family epic set in Birmingham, England in 1919, just after the First World War. The story centres on the Romani/Irish Peaky Blinders gang and their ambitious and highly cunning boss Tommy Shelby (played by Cillian Murphy). The gang comes to the attention of Chief Inspector Major Chester Campbell (played by Sam Neill), a detective in the Royal Irish Constabulary sent over by Winston Churchill from Belfast, where he had been sent to clean up the city of the Irish Republican Army (IRA), communists, gangs and common criminals.

The second series is set two years after the first and sees the Shelby family expand their criminal organization in the "South and North [of London] while maintaining a stronghold in their Birmingham heartland." It begins in 1921 and ends with a climax at Epsom racecourse on Derby Day in June 1922.

Series three is set two years after Series two, in 1924. It follows Tommy and his family as they enter an even more dangerous world as they once again expand, this time, internationally.

One year after a rift divides the Shelbys, they become targets of a Mafia vendetta, forcing the family to reunite and seek help from a shady new ally.

A notorious gang in 1920s Birmingham, England, is led by the fierce Tommy Shelby, a crime boss set on moving up in the world no matter the cost. In season 5, as the Shelbys grapple with the 1929 stock market crash, Tommy confronts new threats to his power from younger family members and fascist rivals.
