Netflix just released a trailer for its new series Marianne, and this witchy new show will most definitely have you spooked.

It may not be October yet, but that doesn’t mean it’s too early to get into the spirit of Spooky Season, right? In that vein, Netflix has released a trailer for its new show, Marianne. The French show looks utterly terrifying and is the perfect series to usher in the Halloween season.

You can check out the trailer below, but you might want to do so with the lights on.

Marianne follows a novelist who realizes the terrors in her novels are coming true. She returns to her hometown to face the demons that inspired her books–namely, a witch named Marianne who haunted her dreams from childhood–and she finds herself in a life-or-death showdown.

From the looks of this trailer, Marianne is going to be a great new series for horror fans. There are so many moments in the trailer alone that are deeply unsettling and utterly terrifying that we can’t wait to see how the entire show plays out.

Netflix has been doing a great job introducing viewers to movies and shows from around the world, especially in the horror genre. With offerings like the Arabic-language supernatural series Jinn, the German series Dark, and the Indian series Typewriter, Marianne is joining a pretty impressive lineup from around the world.

It’s great to see Netflix bringing us another great horror series this year, especially since season 2 of the Netflix original The Haunting of Hill House, called The Haunting of Bly Manor, isn’t set to release until 2020. And if the trailer for Marianne is any indication, this show will absolutely meet our spooky needs.

You can check out Marianne when it premieres on Netflix on September 13. Be sure your queues are ready and you’ve got the lights on!
