Will, who loves to play at being a warrior, is excited when his father tells him about God's armor and that there are real enemies to be fought, both in the world and in his own heart.

When young Will, seeking adventure while visiting his grandparents, hears strange noises coming from a cave and leads "Detective Ralph," his dog, to investigate, even though Papa said to wait for him, he comes to understand more about God and being obedient.

Will finds a piece of a treasure map in a bin of used books, and when he goes back to search for the rest of the map, the bookstore owner shows him that the real treasure in life is found within the Bible.
