Her Lord and Master: Indiana Stillwater, the daughter of a wealthy American railroad industrialist, marries English nobleman Viscount Canning and travels to England. Her in-laws are somewhat shocked by her casualness in dress and manner, but welcome her into the family anyway. When her parents invite her to a Sunday-night dinner at their hotel, however, her husband--believing it to be inappropriate behavior for the wife of a nobleman--orders her not to go. Complications ensue.
