A tight-knit band of boys spend a summer trip in a northern camping region where they reconnect with local Indigenous children, attend a forest Sunday school held in an old rail coach, and pass the days with fishing, canoeing, and woodland explorations. Their easygoing adventures shift to suspense when moonlit screams and strange sounds lead them to uncover a kidnapped girl, prompting a risky nighttime search and confrontation. The narrative blends youthful camaraderie, outdoor humor, practical problem-solving, and a modest moral focus on courage and responsibility.
