A TV producer sees Old Tom causing mayhem at a shopping centre and, thinking Old Tom is a comic genius, gives him his own TV show. Soon Old Tom is a TV star, and everybody who previously disliked him know wants to be his friend - even Lavinia. When Old Tom is mobbed by fans at the Department Store, Lavinia rescues him and takes him to a party she is throwing in his honour. Old Tom enjoys this adulation until he realises that his old friends - Angela and Lucy - are being left out. Old Tom turns his back on his new fame and new friends, and goes back to being himself.

In the final episode, Old Tom seems to be back at square one - rejected by much of the community. On a trip to the observatory, Billy causes trouble but Old Tom gets the blame, so he runs off and hides in his old rocket ship. When Billy accidentally unleashes an asteroid which threatens to destroy the world, Old Tom takes off in the rocket - with Lucy and Angela - and manages to avert the catastrophe at the last minute. Old Tom lands the rocket back on Earth, in the middle of Lavinia's party, where he is finally appreciated for who he is - wild, free-spirited and occasionally berserk - but always a hero.

Angela tries to get her old car repaired, but is talked into trading it in for a new car, instead. The salesman persuades Angela and Old Tom to test drive a sports car, but Angela drives so timidly that Old Tom floors the accelerator. The car zooms through town, attracting the attention of a traffic policeman who gives Angela a ticket. Angela returns the sports car and next tries a four-wheel-drive. But that is too powerful, so she tries a limousine which is so sophisticated she can't even drive it. Eventually, Angela decides to keep her old car, but learns it has been taken to the wrecker's yard. So Old Tom has to race off and save it.

The Queen, wanting to see someone different at her next garden party, choses Angela and Old Tom at random. Angela is delighted, but gives Old Tom a crash course in manners, just in case. The garden party begins, but the Queen doesn't want to go, because her dog doesn't seem well. Meanwhile, Old Tom upsets several party guests and seeks refuge from them in the palace. There he annoys the Queen's dog, which chases him around the throne room. The Queen enters and, delighted to see her dog full of life again, decides to go to the garden party after all - with Old Tom as her guest of honor.
