Thirty years have passed since Greta Marchmont left the Marchmont Hall. Now she finally returns, with amnesia and no memory of her past. But a walk through the wintry landscape leads to a disturbing discovery: she comes across a grave in the forest, and the weathered inscription on the cross tells her that her own son is buried here. Greta begins to search for the woman she once was and to do so, she must summon all of her courage.
