"Little Sisu belongs to a flock of rare golden crows that live in a distant valley. However, the birds' quiet life is beginning to change-giant machines that cut down forests are coming closer and closer.

Sisu's grandmother Una wants to teach him important lessons about life, including the crows' traditional songs and language. The flock is among the last of their species, and Grandma worries their unique songs and customs will disappear forever.

Then little Sisu takes on a big task, a journey that is not only important to his grandmother but also to the future of all golden crows."
