In Summer, one man visits a mysterious island off the British coast and finds a colony of inhabitants intent on preserving their home at any cost.
In Winter, a strong-willed outsider arrives on the island looking for answers, but instead triggers a battle to decide its fate.
It's billed as a limited series. To me, that means it will have a beginning and an end within one season. That's fine if it's good. It will be like reading a short story instead of a novel.
