In this third season Belle (Billie Piper) is attempting to juggle three very seperate identities: Hannah, a high-class independent escort and a published author. For her, it is a continual battle to conceal all her different lives.

That conflict is made more difficult when her sister Jackie (Joanna Bobin) comes to stay. Matters become even more complicated when Jackie starts to go out with Hannah's ex, Ben (Iddo Goldberg). Meanwhile, Bambi (Ashley Madekwe) falls for a client, the hedonistic, young aristocrat Byron (David Dawson).
It appears that everyone has a partner, except Belle.

Only one man really "gets" her - Duncan (James D'Arcy), the editor of her book. As Belle embarks on ever more extreme experiences to provide "good material" for her book, she finds herself drawn to Duncan. She hopes that an (unpaid) relationship with a man could have a future. Duncan knows everything about her. But does Belle know everything about Duncan?

Belle is about to find out...
