A terrible crime is about to happen. Jennie knows it and so do her pets – Dave, the Border Terrier, and Milo the cat.
Dave is calm and sensible, but Milo is the opposite. He is scared of everything that cats are meant to love, and has never been outside in his life! Milo is frightened of mice and terrified of heights. He is often misinformed, his view of the outside world stems only from watching too much TV.
So when Jennie needs someone to help her prevent the inevitable, terrible crime, does Milo have what it takes to help her when she needs him the most?
