While British Lieutenant Warren Somerville recovers in an American army camp, his heart is changed by God's love. Encouraged in his new life by two godly men, he begins to appreciate the value of friendship and compassion. A Christmas letter from one friend's young sister touches him deeply, and he begins a long-distance courtship of Mercedes Jones that lasts six years.
Mercy enjoys corresponding with the British soldier and dreaming that someday he will come for her, but when Warren does appear at her door, the prospect of marriage to a virtual stranger frightens her. He is now a handsome, polished clergyman; Mercy is an ordinary country girl. What can she offer such a man?
