The Sailor Takes a Wife (movie, 1945)

While waiting in New York City to ship out to Europe, a sailor stops by a serviceman's canteen and meets a USO hostess. They immediately fall for each other and get married that night. However, when the sailor is notified that he has been reclassified as 4-F (unfit for service) by the Navy and then discharged, he and his new wife realize that, having to set up house before they expected to, they actually know very little about each other. Complications ensue.
