In a beautiful German village, an old donkey makes the fateful decision to leave his job and go to the city to fulfill his old dream of becoming a musician. Along the way, he meets new friends: a dog, a cat, and a rooster, all of whom share the same dream and face similar problems. But their journey takes an unexpected turn when they find themselves in front of a house inhabited by evil thieves. Will the four friends be able to defeat the thieves, save themselves, and form their band? It's a charming story about friendship that doesn't know despair, and about the power of music to give courage to those who have lost it, spread peace in hearts, and make seemingly impossible dreams come true.
