Robert the Marquess of Haverton desires a chaperone to keep from falling prey to the married, widowed, and single ladies of London. The Duchess of Waverly is sympathetic to her son's predicament and helps him find a suitable female to fill the position.  Miss Catherine Hayward accepts this unusual job. She is surprised to find that the need to keep her new charge from being compromised is genuine. It isn't long before her sympathetic and protective feelings give way to more pleasant, fanciful notions of sharing his company. Soon Catherine finds herself falling for her employer, the Marquess, which makes her the exact type of woman from whom he is to be protected.
