Plot
Percy is alone at Tidmouth Sheds when the Fat Controller's carpulls up. Percy is very surprised to find Lady Hatt instead of the Fat Controller. Lady Hatt explains the Fat Controller has lost his voice, so he is off sick today. Lady Hatt tells Percy to give some of the engines their instructions; Edward is to pull trucks of china plates and cutlery to Brendam Docks and must go slowly and carefully, James is to shunt coal trucks at the coaling plant and must be as busy as a bee, and Henry must collect holidaymakers from Maithwaite, take them to the Scottish Castle and be as fast as Gordon's express. Once Lady Hatt leaves, Thomas arrives and Percy tells him that he is controller for the day. Thomas asks if Percy needs any help, but Percy neglects his assistance.

Percy finds Edward at Knapford and tells him to pull slow goods. Edward is not very happy about this. He finds James at the washdown and tells him to be a busy bee. James gasps and asks if he has to be repainted yellow and black. Percy says yes and sternly puffs away. Finally, he finds Henry at Wellsworth and tells him to pull Gordon's express. Henry is very surprised as Percy puffs away.

Percy then goes to check up on the other engines. At a bridge, Percy says hello to some children, but the children are laughing at Edward being slow and James the stripy-bee engine. Toby arrives with the express, and then they notice the children and Percy. Edward tells Percy that he is meant to be fast, not slow, James tells Percy he's meant to be red, not yellow and black, and Henry explains that he, being a large engine, is not suitable to take the express. Percy realises that he is in a muddle and when Thomas arrives, Percy asks for his help. Thomas suggests to go back in his tracks; he might find something that may help him remember. Percy thinks this is a good idea.

Thomas and Percy go to Knapford to find see Edward's cargo of china. Percy remembers that Edward is to take trucks of china to the Docks. At the coaling plant they see trucks waiting for James to shunt them. Percy remembers that James is to be as busy as a bee shunting trucks. Finally, at Maithwaite, they see holidaymakers waiting for Henry. Percy remembers that Henry is to best as fast as Gordon's express while taking holidaymakers to the Scottish castle. Thomas congratulates Percy for remembering all three jobs.

At last, Edward, James, and Henry are doing the right jobs and that evening, the Fat Controller congratulates Percy for being really useful. Percy is just happy that the Fat Controller has found his voice and hopes that he will never lose it again as being controller for the day was harder than he thought.
