Netflix has released the first Eli trailer for the upcoming horror film, which is a mashup of a psychological thriller and a haunted house movie. Directed by Ciarán Foy (Sinister 2), the film stars Charlie Shotwell?as a young boy plagued with an unknown illness that causes him to be allergic to the outside world. After living his life inside a sealed-off environment, his parents put him in the hands of a doctor (Lili Taylor) whose new treatments promise to heal the boy. But are these treatments actually helping or hurting, and is the secluded hospital housing haunted secrets of its own?

The trailer is effective, and again this looks to be a mashup of a “what’s really happening?” thriller and a haunted house movie, with Netflix clearly trying to draw parallels to the supremely successful anthology series The Haunting of Hill House. The film doesn’t look to be breaking the mold in any way, but it also looks like a film that’s an easy "sure" if you’re looking for something spooky to check out on Netflix—especially as the quality horror offerings are becoming fewer and farther between.

Here’s the official synopsis for Eli:

ELI is the story of a young boy plagued with an unknown, debilitating illness that requires him to live completely sealed off from the outside world. After exhausting every option, his parents put their trust – and his life – in the hands of a doctor whose experimental, cutting edge treatments at her clean house facility may hold Eli’s last hope. As Eli undergoes the tremendously intense process that could potentially cure him, he begins to be haunted by experiences that make him question who he can trust and what is lurking inside the house.
