Vulture pretty much killed it by describing upcoming psychological thriller Before I Go to Sleep as a combination of the Adam Sandler Drew Barrymore comedy 50 First Dates and Memento. If that offers no explanation then let us help.
Before I Go to Sleep stars Nicole Kidman and Colin Firth as a married couple dealing with Kidman’s memory problems. (Her memories are erased every night she goes to sleep.) But soon she starts to get her memory back and remembers being viciously attacked. By whom? We don't know, but signs point to the husband. Watch as Kidman grows distrusting of her husband and tries to remind herself of the truth before it's too late.
P.S. It's always the husband.
