Singers Bob Wallace and Phil Davis join sister act Betty and Judy Haynes to perform a Christmas show in rural Vermont. There, they run into Gen. Waverly, the boys’ commander in World War II, who, they learn, is having financial difficulties; his quaint country inn is failing. So what’s the foursome to do but plan a yuletide miracle: a fun-filled musical extravaganza that’s sure to put Waverly and his business in the black!
