Thomas is chosen to deliver Sir Topham Hatt's brand new car to the Sodor Show. When Gordon challenges him to a race, Thomas is so determined to win that he doesn't wait for the workmen to couple up the car's flatbed properly. He pushes the car as fast as he can. He races to the top of Gordon's Hill only for the car to race down the other side without Thomas. Thomas chases as the runaway car hurtles along the track. Other engines have to avoid the speeding car causing chaos! The flatbed hits a bump in the track and the car lands in a big haystack. Thomas feels silly and, even though he loses the race, asks victorious Gordon to help him fetch Rocky to lift the car from the haystack. The two friends make sure Sir Topham Hatt's car makes it to the show on time! Thomas is at the fitters' yard before a special job taking the school choir to a concert. When James teases him, Thomas becomes determined to prove that he hasn't broken down and puffs away to collect the choir before his final inspection. Soon, however, nasty noises start coming from Thomas' engine. Thomas denies that there is anything wrong and puffs on. Eventually he breaks down. Thomas feels very silly. He asks James to help take the choir to the concert on time. Henry shunts Thomas to the fitters' yard to be repaired. And this time he waits patiently for his final inspection.
