Ma and Pa Kettle help lumberjack Brad Johnson turn his wealthy girlfriend Sally Flemming into a good farm wife.
Worried that her father may oppose her marriage to a lumberjack, Sally hides out on the Kettle farm until Brad can convince her father that he'd be a suitable breadwinner.
Ma Kettle decides Sally needs some heavy-duty lessons on how to be a good farm wife.
Only Sally's sense of humor helps her survive the lessons, which include getting up at 4:30AM; being surrounded by livestock; and mastering the use of non-modern appliances. The wedding does take place in the end.
