Demand for TV sets is high due to Christmas and the upcoming message from her majesty the queen, and especially one customer, Jim Brody, is set on getting a new set - in colour. But only if he gets the very first colour TV set in the area. That is one of the reasons why Rex Hawkins TV rentals and repair shop is very popular and Hawkins is also very popular among the wives of his customers. But he is bullied by Lol Baxter because has failed to pay for a shipment of very cheap, but defective TV sets. Also PC Ventress carries a grudge against Hawkins because Hawkins got him sacked from the local choir. So when Hawkins is attacked outside the Aidensfield Arms there are a lot of suspects to choose from.

Bernie's old friend Stanley Leroy checks in at the Aidensfield Arms. Leroy is a producer and knows all the stars and they organize a s fan club tour, where people can meet their idols. Edna Bostwick reports an intruder at her neighbour Mrs. Carlton's house, but the house is empty when PC Ventress comes to investigate. The next day nurse Bolton surprises a young boy hiding in the house, but he runs away before she can stop him. He leaves behind a shirt with the logo of a nearby boarding school. PC Bradley checks out the school, but the headmaster is of no help except for the boy's name, Tom Bamber. Another guest at the Aidensfield Arms, John Wilson, is also very interested in the house and the boy claiming to be his house master. PC Bradley thinks something is wrong about Wilson - or Monks as he now introduces himself - and the school.
