After their arrests in the third season, Polly, Arthur and Michael spent six months in prison. They were finally out. However, the family was fragmented. Michael returned to work for the Shelby Company, but John and Arthur bought country houses and tried to live quiet lives, and Polly was haunted by the spirits of the dead.
At Christmas 1925, the Shelby family received a mysterious letter, and Tommy understood they were all in danger. Luca Changretta came from New York to avenge his father's death.
The Shelby family gathered in Small Heath, in Birmingham. All of them will have to put aside their dispute to fight together for their survival.
