Mark, Viscount Eaton, is to wed Lady Elizabeth Litten. Theirs is not a love match, but one of mutual convenience. Then a drunken evening results in Mark being pressed into service in the Royal Navy. He must do his utmost to get to the church on time, and avoid the scandal of appearing to reject his bride at the altar. But Elizabeth, having recently met the handsome Frederick Stafford, is having second thoughts about the wedding. Meanwhile, Mark has made the acquaintance of Admiral Milton's charming daughter Diana.
