When a stuck-up and privileged lady of a wealthy family is left to fend for herself, her butler decides to teach her some overdue humility through BDSM.
Kanako meets a BDSM artist, who teaches women an extreme form of erotic submission - how to act like female dogs. It's ruff and he even brings a real dog for her, but she goes with it. This improves her and her geeky husband's marriage.
