As the 1920s begin to roar, business is booming for the Peaky Blinders gang. Shelby sets his sights on wider horizons and his meteoric rise brings him into contact with both the upper echelons of society and astonishing new adversaries from London’s criminal world. All will test him to the core, though in very different ways. Series 2 begins with the Peaky Blinders looking to expand their operation into London but they upset some powerful people in doing so. Later, Polly steps up her search for her missing son, Tommy initiates his plan to take over the southern racecourses, and the Peaky Blinders make a serious move on London's Eden Club.
