In 1912, three young women from wildly different backgrounds are bound together by their desire to have a say in their future.

Charlotte, disappointed to discover that college isn't the key to the freedom she longed for, shocks her family when she moves to London and joins a group of suffragettes willing to upend social norms for the vote. Aristocratic Beatrice, with a law degree she legally can't put into practice and a fiancé she's not particularly excited to marry, escapes to London to spend her last months of unmarried life with the suffragettes, and falls deeply—and dangerously—into forbidden love. Emily, the daughter of the warden of the infamous Holloway Jail, grieves her mother and saves her wages for a better life outside the prison's walls. Her best chance at escaping the drudgery of her life is to stay out of trouble, but when the suffragettes land in her father's cells, she must consider risking not only her family's livelihood, but her own future.

With the dangerous stakes of the suffrage campaign becoming a fight for the women's bodies and lives, they enter a treacherous world where the laws and justice system are stacked against them. They face violent protests, hunger strikes, and brutal forced feedings, and the women must decide how much they are willing to risk for their freedom and for each other.
