Moving to London to start a new career, shy young Philippa is happy to accept a houseshare with a young couple, Jack and Jenny, little realising the extent of the depraved games of bondage and submission they like to play. When she wakes one night to hear Jenny's cries of pleasure as Jack chastises her, she goes to investigate. And so begins Philippa's journey, an initiation into new realms of perversion, taking her to the limits of her own ability to submit - and to the heights of debauchery.
