A Thousand Blows follows Hezekiah and Alec, two best friends from Jamaica who find themselves thrust into the vibrant and violent melting pot of post-industrial revolution London's East End. Drawn into the criminal underbelly of the thriving boxing scene, Hezekiah meets Mary Carr, leader of The Forty Elephants – the notorious all-female London gang – as they battle for survival on the streets. As Hezekiah sharpens his new skills, he comes up against Sugar Goodson, a seasoned and dangerous boxer played by Stephen Graham, and the two are soon locked into an intense rivalry that spills out way beyond the ring.
