Hulu released a trailer for its upcoming series based on Zakiya Dalila Harris’ The Other Black Girl.

Harris’ novel, published in 2021 by Atria, follows Nella Rogers, who is the only Black employee of publisher Wagner Books, until Hazel-May McCall joins the staff. Hazel quickly becomes a star in the office, and Nella starts getting anonymous notes demanding she quit her job. In a starred review, a critic for Kirkus called the novel “a biting social satire-cum-thriller; dark, playful, and brimming with life.”

The series adaptation stars Sinclair Daniel (Insidious: The Red Door) as Nella and Ashleigh Murray (Riverdale) as Hazel. Directors include Mariama Diallo, Aurora Guerrero, and Naima Ramos-Chapman. Harris and Rashida Jones are among the executive producers.

The trailer opens with Nella fielding requests from coworkers to get them coffee and painkillers. A Wagner employee named Maisy (Alyshia Ochse) introduces Nella to Hazel. “It’s just really nice that you’re here,” Nella tells Hazel later, to which she replies, “Right back at you.”

Nella begins noticing that something’s amiss, discovering that she’s being subjected to surveillance and finding a note that reads “LEAVE WAGNER NOW.” Toward the end of the trailer, there is a shot of Nella in an elevator seeing a strange image in a reflection in the metal doors.

Other cast members of The Other Black Girl include Brittany Adebumola (4400), Bellamy Young (Scandal), Hunter Parrish (Weeds), and Eric McCormack (Will & Grace). It is scheduled to premiere on Sept. 13.
