Her daughter Florence gives Mrs. Deville bull-terrier Baxter as a surprise present. Although she's afraid of him she doesn't want to give him away because she feels lonely. But Baxter has his own ideas - he longs to be dominated to be challenged - and so he isn't content with his boring life with the old lady. To get rid of her he causes an accident. It works and he's given to the neighbors a young couple. He's happy... for a while. When they get a baby he again takes action.
