Simon and Daphne couldn't be more different. Simon is London's most eligible bachelor, the Duke of Hastings. Daphne is a youthful romantic with no place in Simon's high society world. But the two come together nevertheless to make a deal. Simon is desperate for relief from the constant pressure to get married. Daphne, meanwhile, longs to marry the man of her dreams but requires entry into higher social circles to make her fantasy come true. Seeing they can benefit each other, the two decide to announce a mock engagement. What they don't see is that they are made for each other.
