A hurt pink-haired boy arrives at a mountain police station. His friend Nina is lost up there. How did this all happen?

Nina discovers the pigs' living conditions in Hugo's parents' pig farm. She persuades him to save a sow from the slaughterhouse.

Attacked by thugs, Nina pulls through mysteriously. After losing the car, Nina, Hugo, and Fleur wander into a dolphinarium where they meet Colombe and her team of angry animal rights activists.
