A powerful tale of one woman's desperate journey from grief to acceptance and forgiveness after an accident shatters her life. Francesca Bodin has a near-perfect life as an accomplished music teacher and professional flutist living in the country with her husband, Ben, and their four-year-old daughter, Addie. This ends suddenly when a snowmobiling accident traps the three of them in a frozen lake. Ben escapes, leaving her and Addie behind to die. Francesca believes she sees their dog pull Addie from the lake and drag her into the nearby woods. Desperate to help her daughter, she struggles to emerge from the icy waters and follows them. Once she enters the forest, however, she finds herself trapped in a sinister dream-like world where night never ends, where Addie's whereabouts remain hidden from her, and where she encounters a group of women who, like Francesca, have been left to die and now seek to unleash their revenge on those who have harmed them. When they have Ben in their sights, Francesca realizes that if she is ever to escape this nightmare and save her daughter, she must first save the husband who abandoned them.
