It's off to a mysterious island for Naomie Harris. The Oscar nominee booked her ticket by signing on for the HBO and Sky mystery drama "The Third Day." Harris is set to star in the six-episode limited series alongside Jude Law, according to Deadline.

The story, which comes from creators Felix Barrett and Dennis Kelly, centers on a mysterious island not far from Britain, where a group of islanders live. They're determined to preserve their traditions, no matter the cost. The first three episodes will make up the first half, "Summer," directed by Marc Munden, while the episodes in the second part, "Winter," will be helmed by Philippa Lowthorpe.

Law's character, Sam, will find the island in the first half of "The Third Day," and Harris's character, Helen, will arrive in the second. She's described as "a strong-willed outsider who comes to the island seeking answers. Apparently, her showing up will spark a battle to decide the island's fate.

Harris has been active in films, television, and theater, taking on a variety of projects and genres. She has notably starred in movies such as "Mowgli: Legend of the Jungle," "Collateral Beauty," and "Moonlight." Her work in the latter earned her an Academy Award nomination.

"The Third Day" is written by Kit de Waal and Dean O'Loughlin and produced by Sky Studios, Plan B Entertainment, and Punchdrunk International. The project's executive producers are Kelly, Munden, Lowthorpe, Dede Gardner, and Jeremy Kleiner, and Adrian Sturges is a producer. Production has already begun, and the limited series is expected to premiere in 2020. Viewers who want to join Harris on the island will find the show on HBO in the United States and Sky Atlantic and its streaming service Now TV in the United Kingdom and Ireland.
