New York photographer Julia catches a lucky break when billionaire Mr. Smith shows interest in her resume. He invites her and her husband, Christian, to his 40th birthday party to meet her. Julia fits in perfectly at the upscale party while Christian feels a bit out of place. As Julia wanders around the mansion, she encounters Mr. Smith playing the piano. The chemistry between the pair is immediately electric.
Christian, having lost his wife in the crowd, goes searching for her. When he finds her, he is awestruck at what he encounters. Christian stands and watches as the well-hung billionaire takes his wife on the piano. With a mix of shame and awe, Christian makes the best of the situation and spins the potential affair into a lucrative job for his wife and an arousing proposition, as Christian always gets to watch.
