Charity Stratton's bleak childhood is changed forever when both her parents are killed in a fire. Separated by the authorities from her younger brothers and sister, Charity is sent out to work as a skivvy in a boys' boarding school. Her loneliness and misery are eased when she falls deeply in love with the dashing but fickle sixth-former, Hugh Mainwaring, but when she discovers she is pregnant with Hugh's baby she soon realises just how alone she really is.
