In season 1, as Hezekiah finds fortune and fame through the art of pugilism, he attracts the attention of the infamous Queen of the Forty Elephants, Mary Carr, who sets about exploiting his talents to further her criminal enterprise. Meanwhile the menacing and self-declared emperor of the East End boxing world, Sugar Goodson, determines to destroy Hezekiah whose ambitions to fight in the West End threatens everything he has built. What ensues is a battle of the old world against the new.

One year later, Hezekiah's a shadow of the man he once was whilst Sugar Goodson is estranged from his family and drinking himself to death. Just as Wapping is about to sigh its last breath, Mary Carr bursts back into town with her loyal second, Alice Diamond, to reassemble her gang and reclaim her crown. As always, Mary has a plan; one which will involve all those she holds dearest. And this time it's riskier than ever.
