The Third Day is a story told over six episodes and in two distinct halves. The first – ‘Summer’, directed by Marc Munden, sees Sam, a man drawn to a mysterious island off the British coast where he encounters a group of islanders set on preserving their traditions at any cost. The second – ‘Winter’, directed by Philippa Lowthorpe, follows Helen, a strong-willed outsider who comes to the island seeking answers, but whose arrival precipitates a fractious battle to decide its fate.
