Remember (2017)

It's a horrific crime scene. A couple and their baby are found savagely murdered in their living room. The bodies are covered in blood, but bear no wounds. The couple's 7-year-old daughter, Madeleine, is miraculously unhurt. But the traumatized girl has lost her memory and can't utter a single word. Why was she left unscathed? There's another troubling question: the doors of the house were locked from the inside, and there's no sign of a break-in. Captain Belgarde takes over the case and brings in Marie Kempf, a psychiatrist who lost her own daughter, Lila, several years earlier. Belgarde investigated that case too, ruling it a suicide. Reluctant at first, Marie agrees to help on the condition that Belgarde reopen her daughter's case, which she refuses to believe was a suicide. They strike a deal and Marie takes Madeleine to her house to treat her, hoping to get the little girl to start talking and rekindle her memory.
