Claude Greengrass is the new lollipop man outside the village school, and PC Rowan gets a complaint from Walter Pettigrew that he suddenly and without warning jumped out onto the street just in front of Pettigrew's car. But Greengrass claims that it was Pettigrew who nearly caused the accident and he is backed up by the new school teacher Jo Weston. Jo Weston is concerned about one of her students, Lizzy McGowan, who is late almost every day. Lizzy's mother lives with her boyfriend Derek Ramsey, who is sent to prison for attacking PCs Rowan, Bellamy and Ventress in a fight at the Aidensfield Arms, but he escapes on the way to the prison. And with good reason too, because the next morning Dorothy McGowan is attacked and badly injured in her home. PC Rowan thinks a mysterious man, who showed up in court, has something to do with it.

Harry Schofield's great ambition is that his son Len becomes a professional cricket player, but when Len is not accepted at cricket training, he runs away from home. Joss Harrop has a couple of mares he wants covered, but stud fees have risen and he cannot afford it. Greengrass has a perfect solution to that. They "borrow" lord Ashfordly's race horse Ashfordly Lad for a couple of hours and return the stud before anybody notices it is missing. That is a lot easier said than done. Not getting hold of the horse that is, but returning it!

Michael Harvey is mortally ill and his son Ronnie and his girlfriend Susan is preparing a surprise party to celebrate his birthday, which he knows will be his last. During the party Michael Harvey asks Susan to be his wife. Shocked the young woman rushes out of the house and rides away on her bicycle. On her way home she has an accident and nurse Bolton is suspected of causing it, but PC Rowan thinks that something is not quite right, and Susan's bike is missing.

PC Rowan is thinking of getting a promotion and wants to take his sergeant's exams.

Christmas is near and there is the traditional nativity play at the village hall with PC Ventress as Santa Claus. Greengrass is supplying half the village with geese, but demand has been higher than expected and he is four birds short. He sends David to pick them up, but the snow causes him to drive off the road and he has to continue on foot to get help. David is not the only one in trouble because of the weather. A bus full of old people from Elsinby gets lost, and Phil Bellamy, who is giving Ventress a lift to Aidensfield, gets stuck in the snow. The falling snow also causes a small plane to crash not far from the police house and Nick and Jo go to see if they can be of any help. They find a very pregnant woman, Sophie, in the plane and tracks in the snow indicate that she was not alone.

Somebody tries to break in at Jean and Derek Lester's cottage. Derek does not want to report it, because nothing was taken, but his wife is sure she heard voices.

So is Barry Jones, who runs a refuge next door to the telephone box, and Mrs. Ventress' goddaughter Susan. The only common denominator to all three of them is Derek Lester who becomes the prime suspect, but he is being blackmailed too.
