Rejected by the woman he believes he loves, the reckless Viscount Sheringham declares that he will marry the first woman he meets. That woman is Hero Wantage, an orphaned childhood friend who has long loved him and accepts his impulsive proposal without understanding the demands of fashionable married life.
Hero’s innocence and Sherry’s immaturity create a succession of social disasters, duels, debts and misunderstandings. Surrounded by loyal but equally inexperienced friends, the young couple must learn responsibility and recognise that affection has grown into a marriage neither originally understood.
