Spywatch

Middle-aged Norman Starkey, a former wartime evacuee, finds his old scrapbook, and decides to write a book about his experience, so he heads back to Westbourne. He recounts being sent off to Westbourne where he meets Cyril Jenkins and another evacuee, Mary Parker. Cyril drives them to Westbourne Hall, home to Phillip Grainger, and his housekeeper, Miss Millington. They refuse to take Norman, but take Mary instead. Norman is driven to nearby Wells Farm where he is taken in by kindly Amy Hobbs, who has recently taken in another evacuee named Dennis Sealey.

Norman and Dennis, both strangers to country life, are put to work on Amy's farm by Amy's granddaughter, Polly, and are both terrified when they find themselves surrounded by cows. Meanwhile, Mary is being forced to do the housework by Grainger and Millington. Grainger also pays Wells Farm a visit and tries to get Amy to move out of the farm, to which he was the landlord, but she refuses.

Amy's cows have escaped and it looks as if the fence has been cut. Norman, Dennis, and Polly suspect Grainger is to blame. Later, the whole village attends a lecture where Cyril Jenkins shows them a series of posters of people who may be spies in disguise, but one poster in particular startles Norman, Dennis and Polly; an image of a woman in half a Nazi uniform and half normal clothing stays in their minds. Meanwhile, in the present, Norman decides to track down Polly.

Luigi Balzoni, an Italian P.O.W, arrives to help on the farm. Amy initially doesn't trust Luigi, but he soon wins her trust. Also, Miss Millington steals Mary's money and accuses Mary of stealing from her. Later, Mary writes a letter to her parents and gives it to Millington to post. However, Millington reads the letter in which Mary describes to her parents how horrible Grainger and Miss Millington are, how badly they're treating her, and begs them to come and get her. Millington throws the letter in the fire.

Norman becomes homesick after receiving a letter from his mother. He goes for a walk by the river and meets Mike Johnson, a lieutenant from the nearby U.S Army base who shows him how to fish. Meanwhile, Mary agrees to help Polly and Dennis find out if Grainger is a spy. On the way back to the Farm, Polly and Dennis encounter a strange woman who bears a striking resemblance to the woman in the poster Cyril Jenkins showed them. When the woman asks for directions to the village, Polly, convinced she's an enemy spy, intentionally sends her the wrong way and thinks they've seen the last of her - until she turns up at the front door!

The mystery woman introduces herself as Vivienne Belling, and she claims to be a government photographer. However, the kids are suspicious of her. Meanwhile, Mary overhears an interesting conversation between Grainger and Miss Millington. Mike gives the children chocolate which is rationed. Also, Polly and Dennis spot a German plane.
