The Lost Patient is a French psychological suspense film by Timothé Le Boucher. Nineteen-year-old teenager, Thomas, awakens in a hospital 3 years after the rest of his family has been brutally murdered. He is given oxygen once he reawakens. But, as he lies in his hospital bed later, he notices a hooded, shadowy person enter the room.

He is strangled by the enigmatic figure as he gets onto the bed, but it is chalked up to a panic attack. The following morning, his psychologist Anna finds him still in bed. She welcomes him and explains that he has been in a coma and that she is there to assist him. She says that Thomas was stabbed and barely survived, that his family had been slain and that there was also the issue of a missing sister. Thomas begins to experience flashbacks as they work together to piece together the circumstances that led to the awful attack.

The central mystery of The Lost Patient is what will primarily keep readers interested in the narrative. Unfortunately, the movie itself is a bit of a slow burner, which can make it difficult to sell if handled improperly.

The movie's heavy use of gloomy music, copious amounts of rain and thunderstorms, and his psychiatrist's increasingly grating exposition. The voice-over remarks, "That's unusual, an empty room in the house," when Thomas enters an empty room in a flashback scene.

We don't need to add anything; we can see that already. The end effect is a shallow and uninteresting picture that frequently looks and sounds more like a video game than a movie and is full of cliches that we should have really moved on from by this point.
