Eighteen-year-old Katherine Ramsey travels to London with her family to make her debut into society and hopefully find her future husband. Her overbearing aunt insists that she must secure a proposal from a wealthy young man who is in line to inherit his father's title and estate. But Katherine questions her aunt's plans when she gets to know Jonathan Foster, a handsome medical student and strong Christian who is determined to protect the poor and vulnerable in London's East End.

When a family scandal puts a damper on Katherine's hopes for the season, she has time to volunteer with Jonathan, caring for children in one of London's poorest areas, and romance blossoms. Katherine's faith grows, and she begins to envision a different future with Jonathan. But when Katherine's work in the East End puts her in danger, Jonathan distances himself from Katherine to protect her. A wealthy suitor reappears, and Katherine must choose which path to follow.
