The prince of a small European kingdom, renowned bachelor Rupert Whyte, is in London to enjoy a last bit of freedom before choosing a wife. When he learns about Ariadne's scheme to take a lover, he decides he must prevent her from embarking on such a ruinous course. What begins as a well-deserved reprimand quickly spins out of control when Rupert agrees to give Ariadne a few lessons in lust. But just how far will their passion go? And will their forbidden liaison lead them too far astray to turn back?
