Episode 1/8

Belle introduces herself as a fun-loving call girl whose services do not come cheap. Her business is to understand what her clients are after and deliver it on the double - however bizarre. When a shy first-timer pays her a visit, he's reluctant to admit that he's aroused by the idea of having sex in a stable. But Belle is a professional and takes pride in her ability to satisfy his needs.

Episode 2/8

Aleksandar, one of Belle's new clients, invites her to an orgy for London's rich and powerful. But when she gets there she spots her favourite author Jay Lorre and realises she's going to have to shake off Aleksandar or miss out on a night of passion with her number one fantasy man. However, her scheming is interrupted by a call from the hospital, where her sister has gone into labour.
