1942. Working in the greengrocers and playing the piano in the pub isn't fulfilling 19-year-old Trixie Smith's idea of helping Britain win the war. One day she sees a poster advertising the Women's Timber Corps and decides to sign up -- soon she is on her way to Scotland for four weeks of training to become a Lumberjill. On her journey north she meets Cy, an American soldier on leave. Their attraction is instant and although their time with one another is brief, they promise that they'll be together as soon as the war is over. But training to become a Lumberjill is hard; felling trees and hauling timber is dangerous and exhausting. Luckily Trixie quickly makes friends with three of her fellow Lumberjills. Each of them has different reasons for signing up, but running away from your problems doesn't make them disappear.
