Three cousins (Carmen Miranda, Michael O'Shea, Vivian Blaine) must travel to Kentucky to claim Magnolia Manor, a plantation they have inherited. They are disappointed to find it in shambles. But things start to look up for them when Sgt. Rocky Fulton offers to fix up the place, on one condition: that they make it into a boarding house for military wives. To raise funds, they decide to perform various musical numbers, and, in the midst of preparations, a love affair begins to blossom.
