Fran awakes to her baby’s cries one February night and finds the bed empty beside her. Her husband, Nathan, is gone. Moving uneasily through the house, Fran makes a devastating discovery that upends her marriage and any semblance of safety. Trying to piece together what happened to Nathan, she delves deep into the undercurrents of his claustrophobic hometown and questions how well she knew her husband in the first place. Fran, increasingly isolated, grows paranoid—but Nathan isn’t the only one hiding something. Indeed, she is shielding a damning secret of her own: a hazy, dreamlike memory from the night of Nathan’s disappearance that might be the key to it all.
