Netflix is gearing up to release a new true crime docuseries focused on a 12-year-old cold case. The Disappearance of Madeleine McCann is about one of the most famous missing child cases in the world, and based on the newly released trailer, it looks haunting.

According to Netflix, the eight-part series tells the story of a 3-year-old British girl who vanished from her room while on vacation in Portugal in 2007. It will be available to stream starting tomorrow, March 15th. The documentary reportedly features interviews with more than 40 new subjects, along with archival news footage and reenactments of what happened.

The trailer, which was released today, March 14th, doesn’t reveal much about new developments in the case, but it does present some ominous theories. One interviewee says that, “statistically, it’s likely to be someone who was in close proximity to the child,” while another brings up human trafficking as a potential (and upsetting) possibility. The trailer closes with a haunting look at boxes of evidence on the case.

Madeleine’s parents, Kate and Gerry McCann, declined to participate in the documentary. In a statement on their website, they explained that they felt it could “hinder” the ongoing investigation into their daughter’s disappearance.

Variety notes that many of the subjects who did participate in the docuseries are investigative journalists who have worked on the case. The filmmakers also spoke to Gonçalo Amaral—who is the investigating coordinator with the Policia Judiciara in Portugal—and former suspect Robert Murat. The series was directed by Chris Smith, who was also behindFyre: The Greatest Party that Never Happened, and it was executive-produced by Emma Cooper.

This is definitely one to watch if you’re a true crime aficionado.
