At the top of an ancient oak, a raven is imposing his rules on all the other birds. What will become of their different birdsongs and plumages?

At the top of an ancient oak, a dark raven tempts birds with berries, leading them to silence all who differ. Soon, the birds must wear only black and sing the same song as the raven. But when a new crow arrives and challenges this uniformity, curious young birds follow him to a neighboring valley where they rediscover the beauty of diversity and freedom of expression. Amidst vibrant landscapes, they realize that true beauty flourishes in a world where every voice and feathered hue is cherished.
