Jason Mamoa will co-star in the upcoming Sundance Channel series “The Red Road.”

The series centers on a sheriff who’s struggling to keep his family together while dealing with two disparate communities: his small hometown and the nearby Ramapo Mountains, home of the Ramapo Mountain Indians.

The plot will also include a tragedy involving the sheriff’s wife, and what’s being called “an unholy alliance” forged between the sheriff and “a dangerous member” of the Ramapo Indian tribe.

Mamoa will play Philip Kopus, who’s described as a “key” member of the Indian tribe.

The six-episode series was created by Aaron Guzikowski and will be produced by Sarah Condon (HBO’s “Bored to Death”).

The Hawaiian-born Mamoa, 33, played Khol Drogo in HBO’s “Game of Thrones” and has also appeared in “Baywatch,” “The Game” and “Stargate: Atlantis.”

He has two children with former “The Cosby Show” co-star Lisa Bonet.
