This sci-fi thriller based on a podcast by the same name is about Dan (Mamoudou Athie), a video archivist who takes a job to restore a set of burned Hi8 videotapes. When he starts seeing the footage, he discovers that it is from a now-missing woman trying to document a cult in the '90s.
The events of the footage take place in an unassuming apartment building in New York City; after the building mysteriously burned down, many were left dead and missing in its wake. As Dan tries to understand what happened, he uncovers details about the woman filming and something that links even his own family to the fire.
The show is at times more of an unsettling horror than a supernatural thriller, but it features a stunning performance from Mamoudou Athie. It's also notably co-produced by James Wan, co-creator of the Saw, Insidious, and Conjuring franchises.
