Based on the successful novel written by S.J. Watson (published in Italy with the title Non ti Addormentare), Before I go to Sleep tells the story of Christine, a woman who,  as a consequence of a particular kind of amnesia, every morning wakes up without knowing anything about herself or about what  happened the day before. A gripping thriller where nothing is what it seems, with Nicole Kidman as Christine, Colin Firth as Ben,  his husband and Mark Strong as Nash, the psychiatrist who’s trying to help her remember what caused the amnesia.
