With her older sisters miserable in their carefully arranged marriages to wealthy, titled gentlemen, Miss Cleopatra Renfield has vowed to wed only for love, passion, and thrilling excitement. Her family has proposed an arranged match to Leslie Petersborough, Marquis of Hastings, which simply will not do. But the mischievous miss has a daring plan to convince her family that Les Petersborough is really a rogue – and that she is unmarriageable. All she has to do is persuade Les to help.
Always ready for merriment and certainly not ready to settle down, Les thinks Cleo's plan sounds terribly amusing. Her scheme? He is to lead her into the life of a libertine in the hope that her family will call off the nuptials. Soon Cleo has cut her hair, joined in a horse race, and danced the waltz. The ton is abuzz, Les is amused, and Cleo? She has succeeded all too well, for her reputation is in danger . . . but so is her heart.
