The Wooing of Princess Pat (1918)

To stave off war with a neighboring kingdom, Princess Pat of Paxitania agrees to marry Warburg's King Eric. Still very young and rebellious, the new queen finds it difficult to adjust to court life, and when she accepts an invitation to take a ride with the villainous Count Ladislaus, King Eric's patience gives out and he rebukes her severely. The banished count informs Pat's father, the Grand Duke of Paxitania, that she is cruelly abused, whereupon Pat's three brothers set out to bring her back home.
