Fontaine is a woman who always gets what she wants - they call her The Bitch. Now a divorcee and whilst she still leads an extravagant jet-set lifestyle, she no longer has the financial security of being a billionaire's wife and her once-successful London nightclub, "Hobo", is now failing. While on a flight returning to London from New York, she meets handsome Italian gambler Nico. In order to impress her, he pretends he is a wealthy businessman, though he is actually a conman who owes money to the mafia and he covertly uses her to smuggle a stolen diamond ring through customs which he intends to sell in London to pay off his debts. With the mafia now pursuing both Fontaine and Nico, they find themselves falling deeper and deeper into danger but she is not ready to give up her life and sets out to prove that she can beat anyone at his or her own game.
