Inspired by a real female soldier's letters home Rosetta doesn't want her new husband Jeremiah to enlist, but he joins up, hoping to make enough money that they'll be able to afford their own farm someday. Though she's always worked by her father's side as the son he never had, now that Rosetta is a wife she's told her place is inside with the other women. But Rosetta decides her true place is with Jeremiah, no matter what that means, and to be with him she cuts off her hair, hems an old pair of his pants, and signs up as a Union soldier.
