We’re used to seeing The Good Place actor William Jackson Harper in a hellish situation. But things look like they get much worse for his character in the new horror-thriller They Remain which opens in theaters in New York and Los Angeles in early March, with a national release to follow.

Harper and Rebecca Henderson play Keith and Jessica, two scientists who are employed by a corporation to investigate an unspeakable horror that took place at the remote encampment of a mysterious cult. Working and living in a state-of-the-art, high tech environment that is completely at odds with their surroundings, they spend their days gathering physical evidence, analyzing it, and reporting on their findings. The intensity of their work, and their extreme isolation, bring the pair closer. But, when Jessica discovers a mysterious artifact of unknown origin, the dynamic between them changes: secrets are kept, sexual tensions arise, and paranoia sets in. Keith begins to have visions and is unable to distinguish whether they are nightmares or hauntings.
