Cosmos, a restless four-legged friend, has to stand trial for his bestial deeds. After biting three people, he is threatened with euthanasia.

Initially unenthusiastic about her new furry client, the lawyer gradually develops a deep affection for Cosmos - and, of course, for his grumpy owner Dariush.
