Peter and Mariana have been in love all their lives. But one night, Peter makes a choice in anger that forces him to leave her behind. Guilt and fear lead him to the Army, where he becomes Captain Kane, war hero. But even that is not enough to make him forget his humiliation or love for Mariana.

But when Peter is injured in Iraq, he finds himself given a second chance from God Himself. Yet even a heavenly encounter may not be enough to overcome his stubbornness. That task falls to Peter's oldest friend, Father Jimmy, who welcomes the soldier back to Poplar Grove. As Christmas approaches, time is running out for Peter to complete the most important mission of his life: convincing himself that he and Mariana were meant to spread a special message of love to the world.
