Amsterdam, 1631: Sara de Vos becomes the first woman to be admitted as a master painter to the city s Guild of St. Luke. Though women do not paint landscapes (they are generally restricted to indoor subjects), a wintry outdoor scene haunts Sara: She cannot shake the image of a young girl from a nearby village, standing alone beside a silver birch at dusk, staring out at a group of skaters on the frozen river below. Defying the expectations of her time, she decides to paint it.
