Who Goes There! (1952)

United they Staggered, Divided they Fell

When Miles Cornwall returns suddenly to the home he shares with his father and sister in a grace-and-favour house at St. James's Palace, he's amazed to find a pretty Irish girl in his favorite armchair. Intrigued, he turns on the charm but, as she explains her situation, he finds himself unaccountably falling in love with this pretty interloper.
