Northern Germany, 1945. Dead of night and dead of winter, a boy hears soldiers and sees strangers - forced labourers - fleeing across the heathland by his small town: shawls and skirts in the snowfall.

The end days are close, war brings risk and chance, and Benno is witness to something he barely understands.

Peace brings more soldiers - but English this time - and Red Cross staff officers. Ruth, on her first posting from London, is given charge of a refugee camp on the heathland, crowded with former forced labourers. As ever more keep arriving, she hears whispers, rumours of dark secrets about that snowy night.

The townspeople close ranks, shutting their mouths and minds to the winter's events, but the town children are curious about the refugees on their doorstep, and Benno can't carry his secret alone.
