On the Island of Sodor, there is mutual animosity between steam and diesel locomotives. One summer, the Fat Controller announces that a new airport is to be built to accommodate more holiday makers, but Arry and Bert, the twin diesels, biff their trucks into Thomas and Percy at the construction site, angering them. At the timber yard later, they boast to Thomas that they got a very important job because are better than steam engines, and Thomas responds by biffing them so hard, their timber falls onto the tracks. When Devious Diesel confronts them with a similar boast, Thomas retaliates by giving Diesel a train of bananas instead of bricks, but as a result, Tidmouth Sheds, having been demolished for renovations, is not rebuilt on time. As a result, all the engines are forced to sleep elsewhere; Thomas sleeps at Knapford Sheds with Emily, who takes a dislike to having another engine in her shed. That night, a huge storm sweeps across the island and the Sodor Suspension Bridge collapses. The next morning, the Fat Controller orders the engines to clear up the storm damage before the work can continue.
