Chloe sees Mr. Stink every day, but she's never spoken to him, which isn't surprising, because he's a tramp, and he stinks. But before she knows it, Chloe has an unusual friend hiding in her garden shed when it looks like Mr. Stink, and his dog Duchess, might be driven out of town. As Chloe struggles to make sure no one sniffs out Mr. Stink, she also has to cope with an overbearing mum, her put-upon dad who has a secret of his own, her 'perfect' younger sister Annabelle and the nasty girls who make her life miserable at school. And it turns out that there is more to Mr. Stink than meets the eye... or nose.
