A teenage girl is the latest victim in a growing number of bear attacks. Officials must figure out what's causing the bizarre bear behavior or close the park. Can the Landons help? Soon Jack and Ashley are searching for answers with their new friends Yonah Firekiller, a 16-year-old Cherokee boy, and 14-year-old Merle Chapman, whose family once lived on park land.
