A dog's life in the south of France. From puppyhood, Sirius the Pyrenean Mountain Dog has been trying to understand his humans and train them with kindness. How this led to their divorce he has no idea.
More misunderstandings take Sirius to Death Row in an animal shelter, as a so-called dangerous dog learning survival tricks from the other inmates. During the twilight barking, he is shocked to hear his brother's voice but the bitter-sweet reunion is short-lived. Doggedly, Sirius keeps the faith.
One day, his human will come.
