An anxiety-ridden young mother (Noomi Rapace) – so fearful of her violent ex-husband that she uses a baby monitor to listen to her 8-year-old son (Vetle Qvenild Werring) sleeping in their secretly located flat – starts to question her own sanity when she begins to see and hear things that she knows to be not true. But a new friendship with a kindly shop worker (Kristoffer Joner) seems to give her some limited comfort, in Sletaune’s diverting, if rather cold, mystery-thriller. Though beautifully crafted, the film proves disappointingly po-faced compared to his earlier works, concentrating rather too much on plot, with little time given to building interesting characters.
