Thomas races around the island while taking the famous opera singer Alicia Botti to the Town Hall.
Alicia Botti, the famous opera singer, is coming to Sodor. Thomas is bubbling with pride that he is to collect her and take her to the Town Hall for the grand concert. Also arriving that day is a new engine named Charlie. When Percy says that Charlie is more fun than Thomas, it makes Thomas worried. Thomas doesn't want Charlie to think he isn't fun, so when Charlie starts racing around the island, Thomas joins in, but a bumpy track causes Annie and Clarabel to uncouple from Thomas and he puffs off leaving Miss Botti behind. Arriving late and without Miss Botti, Sir Topham Hatt is cross with Thomas. Thomas searches for Miss Botti and finds out that she is having a marvelous time singing to anyone who will listen and more than ready for the concert. While Percy is at the Sodor Steam Works being repaired, Thomas is excited to be given the job of doing the mail run for him. Gordon advises Thomas to ask Percy for advice but Thomas thinks he knows all about how to deliver the mail. He sets off very early in the morning, tooting his whistle loudly wherever he goes. In the process, Thomas wakes up Mavis, Cranky, Victor and Kevin. Later, the sleepy engines make mistakes and Thomas realizes his error. The next morning, having learned a few lessons from Percy, Thomas does the mail run again, this time very quietly.
