Four girls have different reasons for joining the Women's Land Army: patriotic Joyce wants to 'do her bit', argumentative Nancy is there under sufferance, and sensible Annie joined so that her younger sister Bea could escape an abusive father.

Bea rebels from her sister's control and finds herself enthralled by a charming GI, Cal Gillespie, while at the dance Nancy tries to get closer to Lord Hoxley.

Bea has been hiding her pregnancy from everyone for three months, but it is becoming increasingly difficult. Tucker is on the prowl for enemy sympathisers and Nancy is in his sights.

Farmer Finch gets involved in a scam to flog home-made carrot whiskey, while Lord Hoxley realises that his marriage is over - and this drives him into the arms of Nancy. Meanwhile, Tucker finds Annie to tell her the devastating news that her husband has been killed in action.
