London by night. Belle sits in the back of a car and is driven to a party, a swinger party where you only get in with an invitation. Of course she has one. She apparently can’t wait to get there as she likes to go to that party. She’s all dressed up and wears a black wig.
Tonight is the country’s most prestigious adult party. To get in you have to be a couple under 40, educated, and good looking. At the entrance Belle and her client reach the front desk where they have to hand in their phones and other recording devices. On their way up Belle asks if she should pretend to be married, her client declines and he asks her if she remembers exactly what he does for a living. She also tells him that nobody will ask her that question.
Belle picks up a glass of Champagne, but she will not drink: she explains that she doesn’t drink while working. She goes on and explains that an adult party is like every other party. Some want to be in the centre of attention (like the nude one, but painted golden), the shy ones in the corner and the cool crowd who know everyone and the organizers. And the room where the real party happens. The two enter – he thinks it’s quiet, but she tells him that it’s early. She starts to kiss him, but he stops her. He wants to see her get desperate when all the other men want her and maybe have sex with her later on, but not during the party.
When the two go to another room, another guy runs into her so she spills her Champagne. She goes to the bathroom, where she’s concerned as she knows that guy from somewhere. She tries to remember him, but that’s hard as she tries to think of anyone she ever slept with – and that could take a while. When she remembers she explains that it is an author, and she loves his novels – her hero (apparently he wasn’t one of her clients) and she confesses that it’s not the best to meet with your heroes.
She goes over to that guy and starts to flirt with him. After a short while she asks him to go private, when her client joins their conversation and takes her away. He tells her that he will be the only one that can have her (despite the fact that they are at a swinger party where everyone is meant to have sex with everyone).
Later on that night, she’s frustrated as she can’t seduce her writer as she has the only possessive man at the party at her side. So she tries to get another woman (Julia) to talk to her client about some science project so she can run off to her writer. They talk in another room where Belle complains that she hasn’t been in the playroom yet.

Then the show starts so everyone gathers in another room. Alexander is focused on the show, so Belle and Jay go into the playroom for some action. In the middle of the other couples having sex they get on to it too. Meanwhile Alexander still enjoys the show that slowly comes to an end; while Belle and Jay are joined by another woman. Other men start to watch this hot threesome. Suddenly Belle stops thinking about Alexander (her client), so the couple offers her to go home with them.
So Belle decides to ditch her client!
Her drunken client still enjoys his fantasy to give it to her later. She organized one of the waiters to come up to her tell her there’s a phone call waiting for her. She talked with that guy to plan her exit. She wants to pretend something happened, so she could go home with that other couple.
So she tells her client that she has personal reasons, but also lets the couple go – as she listens to her cell phone.
So she goes to see her sister that apparently has given birth. She’s all frustrated as she thinks she missed out on the best sex in her life. Apparently her brother has called her. Her sister has given birth to a boy. Ben finds her wig, but hides it away.
On the roof she finds her dad smoking. He asks what she was doing, but she doesn’t answer and he seems to understand.
Her brother Ben drives Hannah home who falls asleep in the car. When they reach her place he takes out her wig and puts it on his head. He asks some questions, but she shuts him up.
At home she takes off her clothes and goes to sleep (in her professional bedroom not her own). She takes out a book – from her favourite author.
