At the Happy Paws Rescue Centre, every pet dreams of one thing: going home. But Ralph, Mitch, Bessie and Fred are the no-hopers: dogs so difficult or troublesome they aren't expected to ever go home. Ralph's face is scarred. Bessie can't stand to be touched. Mitch can't stop chasing cats and Fred . . . has just given up. Who'd want to adopt any of them instead of a cute little puppy?

But when Happy Paws reviews its policy of never putting an unwanted pet down, time starts running out for the dogs. Can they prove that they're worth a second chance? Will there be hope for the no-hopers after all?
