On top of the highest mountains on Earth lives a plant that feeds on the most perfect sunlight. It is called... the Himalayan flower. Yuku leaves her family to search for this flower of eternal light. She wants to give it to her grandmother who announced that the time has come for her to go with the little blind mole into the meanders of the earth. But to find it, Yuku’s journey will be long and full of obstacles. She has to cross the terrible domain of sewer rats under the castle, the meadow where cruel and voracious crows reside, the enchanted forest where everyone gets lost and, above all, the little bridge of fear guarded by the wolf! Yet on her way, through her music and songs, Yuku makes many friends. They are the most precious ingredient for succeeding in the adventure of life.
