Christine wordt ’s ochtends wakker in een vreemd bed, in een vreemd huis, naast een man die ze niet kent. Ze herinnert zich niets van wat er die nacht is gebeurd en besluit snel haar kleren aan te trekken en naar huis te gaan. Maar dan ziet ze zichzelf in de spiegel. Christine herkent zichzelf niet: ze is veel ouder dan ze dacht. De man vertelt haar dat ze al tweeëntwintig jaar getrouwd zijn.
Nee, helaas is Before I Go to Sleep nog niet beschikbaar op Netflix in Nederland.
