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?
