With the arrival of mid-summer, everyone begins to prepare for the Sun Dance at Eagle's Landing. Joey, who is deep in his studies of the old ways, decides to spend most of the Sun Dance with his Grandpa, learning about the reason the Cheyenne people have a Sun Dance. However, things quickly take an unexpected twist when his cousins Mark and Danny arrive from Oklahoma. Right away, they seem to be outsiders, with little knowledge of the customs of the reservation and an appetite for adventure and jokes. Soon a strange camper turns up at Eagle's Landing, and begins to mess with things. Quickly suspicions fall on the outsiders. However, a strange find up at Eagle's Landing leads Joey to the conclusion that the prankster may be closer to home, much closer! Now, Joey and his friends race to find the phantom camper before he or she ruins the most important ceremony of the year, and shames the entire Red Wolf family.
