What’s it about?
 ‌The show is divided into two parts: “Summer” and “Winter.” In “Summer,” one man (The New Pope’s Jude Law) visits a mysterious island off the British coast and discovers a group of inhabitants intent on preserving their home at any cost. In the second half, aka “Winter,” a strong-willed outsider (Moonlight’s Naomie Harris) comes to the island seeking answers — but instead causes a battle to decide its fate.

‌Who will I recognize?
‌Along with Law and Harris, Katherine Waterston (the Fantastic Beasts films), Emily Watson (Chernobyl) and Paddy Considine (The Outsider) are among the series’ cast.

Who’s behind the scenes?
 The HBO and Sky co-production was created by Felix Barrett and Dennis Kelly. “Summer” is written by Kelly and directed by Marc Munden, while “Winter” is written by Kit de Wall, Dean O’Loughlin and Kelly and directed by Philippa Lowthorpe. The series is executive-produced by Barrett, Kelly, Dede Gardner and Jeremy Kleiner.
