Nevertheless she persisted

Clara and Nancy both have choices to make. Two sisters, working in a women's prison in 1913; many of the inmates they are faced with have been arrested for their actions as part of the suffragette movement. For Nancy, there's one inmate in particular - the enigmatic 'Duchess' - who she finds herself drawn to, following the Duchess' lead into the fight for the right to vote. But for Clara, the choice is not so clear-cut. She's started stepping out with a chap called Ted. But if she were to marry him, she would have to give up the job she loves, and lose her independence forever.
