Carrie-Anne Moss, who has recently appeared in series like "Fubar" and "Wisting," will take on one of the leading roles in "Yaga." She portrays Katherine, a charismatic university professor whose sophisticated demeanor belies a confessed — and intriguing — weakness for younger men. Her character becomes entangled in a complex investigation that delves deep into the supernatural, marking a welcome return for Moss to the kind of genre-bending storytelling that cemented her status as a cinematic icon.

The series centers on Rapp, a private detective, as he investigates the disappearance of the young heir to a powerful fishing enterprise. His search quickly brings him into conflict with Carson, a wary local inspector, and Katherine, the university professor. As Rapp's investigation progresses, he finds himself drawn into a labyrinth of elusive suspects, buried secrets, and ancient forces, where ancestral magic appears to be pulling the strings. The narrative promises an intense fantastic thriller that doesn't shy away from alluring elements, exploring the myth of the infamous witch Baba Yaga within the shadowy corners of British Columbia.

Joining Moss in this intriguing ensemble is a talented cast. Hudson Williams, a rising star recognized for his breakthrough role as Hollander in the series "Heated Rivalry," will play the pivotal role of the missing heir. Noah Reid, known to audiences from "Schitt's Creek" and "Blake Holsey High," is cast as the determined private detective Rapp. He will share the screen with Clark Backo, who recently appeared in "Venom: The Last Dance," as the skeptical Inspector Carson, forming a dynamic investigative duo.

"Yaga" is brought to life by screenwriter Kat Sandler, who serves as the series' creator. Her vision promises a fresh take on the mystery and supernatural thriller, blending compelling character drama with elements of ancient folklore and a modern investigative narrative. The series is poised to be a significant addition to HBO Max's lineup, offering a rich, immersive experience for fans of complex mysteries and the fantastical.

Mark your calendars: "Yaga" is scheduled to premiere on HBO Max on October 23, 2026.
