Rendezvous with Annie (1946)

A homesick American soldier stationed in England during WWII, makes an unauthorized (a.w.o.l) trip on an American Air Force plane to the United States to see his wife, and then hops the plane back to England, with only his wife knowing he was home for a few hours. Later, she learns that she is pregnant and to disclose that her husband had paid her a visit, would get him into trouble, which she doesn't, the townspeople are unanimous in their condemnation of her. But, after her husband is discharged, he enlists the aid of a nightclub singer, the only other person who knew he came home, and the gossips are left to find something else to prattle on about.
