Ada-a woman from Montreal living reluctantly in Michigan-vanishes from her bed one night while her husband Danny is asleep beside her, her young son, Gilles, in the next room. Desperate to locate Ada before Gilles understands what has happened, Danny begins a search. But the feds are already involved: across the country and around the world, mothers are vanishing from their homes. Where did Ada go? What has she gone through? And how does the mystery relate to the forest that she seemed magnetically drawn to?
