Throughout the summer, Brian learns how to survive in the vast wilderness with only his hatchet. He discovers how to make fire with the hatchet and eats whatever food he can find, such as rabbits, birds, turtle eggs, fish, berries, and fruit. He deals with various threats of nature, including mosquitoes, a porcupine, bear, wolf, skunk, moose, and even a tornado. Over time, Brian develops his survival skills and becomes a fine woodsman. He crafts a bow, arrows, and a fishing spear to aid in his hunting. He also fashions a shelter out of the underside of a rock overhang. During his time alone, Brian struggles with memories of home and the bittersweet memory of his mother, whom Brian had caught cheating on his father before their divorce.
