A gangster family epic set in 1919 Birmingham, England and centered on a gang who sew razor blades in the peaks of their caps, and their fierce boss Tommy Shelby, who means to move up in the world.
As the Russians test the Peaky Blinders men in their own distinctive and debauched way, Tommy realises that he is being seriously outmanoeuvred. Desperate for help, he rekindles a business relationship with a dangerous former acquaintance.
