After discovering their troop is in danger of disbanding, Snoopy and the Beagle Scouts set off to immerse themselves in nature and the great outdoors to earn their badges, with the Beagle Scout Manual as their guide. Meanwhile, Charlie Brown and friends enjoy their summer at Camp Spring Lake, crossing paths with Snoopy as they experience hiking, swimming, sitting around campfires, and everything summer camp and the outdoors have to offer.在发现他们的队伍有解散危险后，史努比和比格犬童子军们出发去亲近自然，体验户外生活，以获得他们的徽章，并以《比格犬童子军手册》作为指南。同时，查理·布朗和他的朋友们在春湖营地享受夏天，他们与史努比相遇，一起体验徒步旅行、游泳、围坐在篝火旁，以及夏令营和户外活动的种种乐趣。
