Clara and Nancy both have choices to make. Two sisters, working in a women’s prison in 191; 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.
