Teenaged Wyn Davies took a shortcut through the woods in her New Hampshire hometown and became a cautionary tale. Twenty years later, divorced, she lives in New York making her living painting commissioned canvases of birch trees to match her clients' furnishings. Then she hears that Robby Rousseau, who has spent the past two decades in prison for a terrible crime against her, may be released based on new DNA evidence. Wyn agrees to be temporary caretaker for a friend's property on a remote Maine island, where she discovers a box of film canisters and photographs that will force Wyn to finally confront what happened in those woods.
