Charlotte Stuart is an heiress dedicated to charitable causes who's been betrayed by the false love of a fortune hunter before.
Lord Edward Woodcliff has come to London to find a wife. Made leery of marriage by his father’s disastrous second marriage, his hesitation to make a matrimonial mistake proves difficult to overcome.
All seems hopeless until Edward challenges Charlotte to a wager. If he wins, he gains her hand in marriage. If he loses, then Charlotte is free of him. Charlotte accepts the wager only to lose her hand and her heart to Edward.
