In eighteenth century London, Elizabeth Wilkinson is struggling to make ends meet for her and her sister Tess. While Elizabeth works odd jobs at the local newspaper, her true passion is bare-kuckle boxing. The only way to make enough money off of boxing is to train with one of the famous retired boxers and the only real fight promoter of any notoriety, James Figg. Figg refuses to train Elizabeth at first because she is a woman, but she cunningly forces his hand by taking an ad in the newspaper and claiming that she will fight another female bare-knuckle boxer as Figg’s pupil. As Elizabeth trains with Figg and James Stokes, she is forced to come to terms with her half-Indian side and her criminal father as she faces the powerful female bare-knuckle boxers of her day.
