Hull, 1943. 17-year-old Muriel Dearlove has weathered the Blitz unscathed, earning her keep in Miss Chapman's grocery shop. But with her sweetheart Bill away fighting and and her friends conscripted into the WRENs and WAAF, life has become tedious for Muriel.

Then one day an old friend returns from a stint in the Land Army. She is rosy cheeked and looks healthier than ever, thanks to the outdoor work she has been doing on Northumberland's farms, and she comes with tales of dances with the troops stationed nearby and high jinks with her fellow Land Girls.

Desperate for the chance to broaden her horizons, Muriel signs up to become a Land Girl. But getting back to the land is not all about making hay in the sunshine. Back-breaking work and rising before dawn are the least of their troubles when disagreements between town girls and locals arise, and their warden, Mrs Hubbard, is a hard-nosed slave-driver. Then Muriel meets Ernst, a German prisoner of war. And now Muriel has a choice to make. In fraternizing with the enemy, she breaks the law, but to never see Ernst again would break her heart.
