A poacher shoots; a bear charges; a father and his seven-year-old son flee the scene, but they stumble and plunge into the ravine. Their fall ends when they hit a tree trunk that rebounds them into an overhang. The father is unconscious; the boy has a broken leg.
A vast search and rescue operation is mounted. As a second night of failed attempts to find them sets in, Zita, the mayor of Pianalto, is confronted by a posse out to kill the bear and a town on the warpath calling for the government to review its policy on the protection of the species.
In the nearby peaks, a bear and her three cubs are on the run.
