In the series, Law plays Sam, who is being drawn to a mysterious island off the British Coast and thrown into the unusual world of its secretive inhabitants. Isolated from the mainland, the rituals of the island begin to overwhelm him, and he is confronted by a trauma from his past. As the line between reality and fantasy blurs, Sam finds himself immersed in an emotional quest that puts him at odds with the islanders and begins to threaten their way of life.
Waterston will play Jess, who Sam encounters on the island,
