Michael Farr (Ciarán Hinds), a teacher raising his two kids alone since his wife died two years earlier, has been seeing and hearing strange things late at night. He isn't sure if he is having nightmares, or if he's experiencing a haunting. Working as a volunteer for an international literary festival, he is assigned to Lena Morelle (Iben Hjejle), an author of books about ghosts and the supernatural. Establishing a rapport with one another, Michael opens up and shares his terrifying experiences with her. However, Lena's attention is distracted by another novelist, Nicholas Holden (Aidan Quinn), with whom she had a brief affair. The trajectories of these three people lead them into a life-altering collision where the challenges of love, fear of the unknown, and release from the burden of grief are explored.
