The Cuckoo episode 1 introduces us to Jessica and Nick, who have recently moved into a beautiful, remote property in the countryside with their adopted daughter. However, their idyllic life is soon disrupted by financial issues, and they decide to take in a lodger.
It's a difficult decision, and the couple's 14-year-old daughter Alice is against the idea, not wanting anyone else in their space. But when Sian arrives, the family think they've hit the jackpot, as she seems like a charming new resident to help them balance the books.
