Margot doesn't have time for love. Will is afraid to love. And neither of them are expecting to fall in love with Blossom: a gentle Staffy with a tragic past, a belly made for rubbing and a head the size of a football. After their first meeting at the rescue centre, both Margot and Will want to adopt Blossom so reluctantly agree to share custody. But Will's obsession for micro-managing and clear-cut boundaries and Margot's need to smother Blossom with affection, means that soon they have a very confused and badly behaved dog on their hands. Can they put their differences aside to become successful "co-pawrents" and maybe even friends? And meanwhile, does Blossom have plans of her own?
