Our Hospitality [Buster Keaton] (1923)

After her husband John McKay is killed in an ongoing feud with the Canfield family, a woman takes her baby boy Willie to her sister's house in New York hoping he will never know of the feud with the Canfields. Twenty years later Willie is a grown man and he receives a letter saying he has inherited his father's estate and must travel to his family home to take possession. On the train there he meets a beautiful young woman and falls in love only to learn that she's a Canfield. He accepts her invitation to dinner and quickly realizes that the Canfield men won't kill him while he's in their home. His plan to stay there as a permanent guest is short-lived and the Canfields are soon after him.
