After causing trouble the day before, The Fat Controller has confined Sir Handel to the shed for several days. Peter Sam is now single-handedly running the Skarloey Railway and extremely excited about his new position, despite Skarloey warning him to keep calm. One morning, despite his best efforts, Peter Sam is late to Crovan's Gate. Henry is unimpressed and threatens to leave without his passengers next time. Peter Sam is secretly worried, but soon gets back to work, happy to be running the Skarloey Railway. He begins singing to himself and the coaches happily follow along.
Later that afternoon, Peter Sam makes his scheduled hour-long stop at the Lakeside Station. Whilst there, the crew buy tea and cakes from the refreshment shop at the station. The lady who runs the shop always catches this train home. Peter Sam begins to worry about missing Henry's train as the crew and passengers return. As the Refreshment Lady approaches the platform, Peter Sam suddenly starts, thinking he heard the guard's whistle, whilst the guard believes Peter Sam was simply being too impatient. Whatever the cause was, the coaches quickly tell him of his mistake, causing him to stop and allow the Refreshment Lady on the train.
Fearing that he'll miss Henry, Peter Sam races back to Crovan's Gate as fast as he can. To his relief, he arrives to find that Henry is still there. The Refreshment Lady is cross at Peter Sam and tries to know why he left her behind. Upon hearing his apology and explanation, however, she laughs and explains that Henry was only joking: as a guaranteed connection, he has to wait for the passengers. Peter Sam is furious and is determined to give the larger engine a piece of his mind, but by this point, Henry had already left the station.
