Cerberus, the hellhound of the Underworld, is given the task to accompany his queen wherever she wants to go and she picks modern day London. The duo is ready to indulge in shopping for her and plenty of naked willing ladies for him, only they're greeted in the new world by violence.

Leaving a horrifying mess of blood and bodies behind, they find a hotel and connect with Kate Bentley. As a staff member, she sees that their every need is fulfilled and more with a visit to a lingerie shop. The playful and randy sides of Cer merge together with Kate and he can't shake what he starts feeling for her.

Cer is a dog at heart, but after an erotic show, a kinky bra, Kate calling him Sir, and a couple men from Scotland Yard, there may be too many changes for them to go back to where they were.
