Hazel loves sex. It is her hobby and her passion. Every fortnight she meets up with the well-bred, reserved, and impeccably mannered Alistair. Then there is Nick, the young IT lad at work, who has taken to following Hazel around like a lost puppy. Her greatest preoccupation, however, concerns the mysterious Number Six - the suited executive she met one day in the boardroom, and who she dreams of seducing. When it transpires that Number Six is a colleague of Alistair's, things are destined to get complicated. Especially as Hazel is moving towards the 'unknown territory' her mother warned her about.
