Romana is enjoying a trip to the hair salon when she hears the hairdresser and a customer discussing Suitors, robots that provide certain services for elderly ladies. They also discuss missing pensioners that have been linked to the Suitors. She is shocked when the customer, Maude, calls the robot a "DoctorBot", and her suspicions are confirmed when K9 finds a magazine advert showing a picture of a Suitor — it perfectly resembles the Doctor. The Doctor, Harry and Sarah are confronted by the newer version of Suitor, which is an expert in karate.
