Morgan and Tidbit live in Notch Valley in the North Peaks. They enjoy a quiet life with other Weebitty Bears, but long for a new adventure. While hiking one summer day in the North Peaks, they decide to venture north and explore country where they have never been, and where Hare has never been. Korbin and Vernese join them on their venture. The four Weebitty Bears call themselves The Four Adventurers. The four adventurers plan their venture and practice their skills through the fall and winter, and leave in the spring. Their venture takes them deep into rugged mountains. The few animals they see warn that a bad winter is coming, with bitter cold and deep snow. They find shelter and prepare for winter, but the winter is far worse than they expected. They are alone and struggle to survive the winter and near disasters.
