Young married couple Nicola and Greg have stepped through the doorway to a new dimension in their sexual life, a step that began on Nicola's birthday, when Greg arranged for the surprise of her life and took her to a sex club for an adventure. Thinking it was a simple and sizzling way to relieve their mounting urges, they met up with club owners Jack and Perry, who were more than pleased to show them the way.
When the incredibly wealthy and irresistibly sexy Jack invites them to a party at his home a few weeks later, Nicola begins to see that nothing is simple, but she and Greg are unable to resist, especially because they know this will be no ordinary party. Jack has made it clear what he wants, and what he wants is Nicola. All of Nicola.
Nicola and Greg now have to learn the rules of this steamy lifestyle, and decide if they can follow them. Is it really, as Jack says, just a game?
