Inventor Robert Sommerby and his aunt are visited by a man from the ministry who wishes to offer government funding for his robots. Unfortunately a rival group have hired a private detective to spy on Robert and his creations.
Robert and his aunt are concerned that the robots have been given too much emotion - Eric is becoming increasingly rebellious, while Katie has fallen in love with the new gas cooker.
Gimble continues to spy on Robert's lab, but, after seeing him repairing his robots while listening to a radio drama about a spy being interrogated, he mistakenly believes they're real people who Robert is torturing.
Robert creates four new robots as part of his inventing work - programmable entertainment robots that can perform a variety of styles on demand. Unfortunately for Robert, they cause him more trouble than ever.
The Minister is coming to visit Robert to discuss his future development plans. As it was the Minister's Office who recommended an increase in his funding, Robert conducts an inspection to make sure the robots are in top condition.
Eric's emotion circuit has been adjusted, making him a more empathetic, kinder robot. With his new-found sensitivity, Eric decides that he and Katie should enter the caring profession - with Robert as their first unwilling patient.
With the robots due to help out with a new fashion parade, Robert unveils his latest idea - robot doubles for everyone, starting with himself. Unfortunately Eric has organised a robot union, and taken all the robots on strike.
