Escaping the constraints of life as a village schoolmistress, Lilia Brooke bursts into London and into Paul Harris's orderly life. Lilia wants to change women's lives by advocating for the vote, free unions, and contraception. Paul, an Anglican priest, has a big ambition of his own: to become the youngest dean of St. John's Cathedral. They know they don't belong in each other's worlds, but they can't deny their attraction.
