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.

A new girl, Connie, arrives at the farm and sets her sights on Billy. The manor house has been commandeered by the Americans, which excites Lady Hoxley's sister, Diana (Raquel Cassidy). John visits Joyce at the farm and Martin has an accident. Tucker is released from prison. Finch enters his pig into a county show, so it can avoid slaughter.

Following his fall, Martin is found to have detached retinas. He is also hiding an injured man. Diana tries to help Jack find his grandson and Joyce receives bad news about John. Finch tries to keep his contraband deals from Mrs Gulliver (Carolyn Pickles). Bea becomes friends with Salvatore Zappulo (Cesare Taurasi), an Italian POW, while Connie flirts with piano player, Henry (Liam Garrigan).

Danny threatens to hurt Henry if Connie doesn't submit to his will. Ellen considers if she can trust the man she loves. As Joyce and John grow closer John struggles with guilt over his infidelity. A revelation drives Martin even further away from Esther. Iris is in mourning whilst Walter and Frank square up for a fight with disastrous consequences.

Events spiral out of control for Connie when her shady past catches up with her. Iris makes a shocking discovery, whilst John is given some crushing news and Esther decides to face her critics in the village. Meanwhile, can Ellen keep up the pretence with Richard?
