After a windy night, the sun rises. Two fuzzy bundles of red fur wake up in a hidden burrow in a remote forest. But an unexpected visitor calls on the family and, praising the qualities of the two cubs, full of energy and vitality, encourage them, driven by curiosity, to search for food on their own and to explore beyond the safe confines of the valley. Following what they believe to be someone they can trust, they will embark on a dangerous adventure where their lives will be in grave danger. Exposed to even more dangerous and threatening creatures, they will discover that all is not yet lost, and they have a unique sense of smell that could save them. Will they still have time to listen to their instinct?
