The engines are all excited that the Mallard is coming to visit the Island of Sodor. All, except Gordon, who is jealous of the Mallard for breaking his speed record. When the Mallard arrives the next day, Gordon angers the other engines with his rudeness and nonsense that he went 130 miles per hour. The Mallard tries to be kind to him but Gordon's jealousy gets the better of him. After being held up at Crosby to let the Mallard pass by for photographs, Gordon is absolutely furious. On the way back from Crosby, Gordon attempts to break the Mallard's speed record of 126 miles per hour. Gordon races by Donald and Douglas, who wonder what Gordon is doing. He becomes so oblivious to where he is going while trying to do this, and is headed for disaster.
The signalmen hasn't expected Gordon so early, so the points are headed to the harbor. By the time Gordon realizes this, he is going way to fast on the docks and slips on the rails, runs off the end of the pier, and tumbles into the sea. James and Duck are quite amused at Gordon's stupid accident and they think it serves him right for being a baby about speed until the Mallard says it's not something to laugh at and points out that there will be no way to rescue him. Sir Topham Hatt states that no crane is strong enough to lift him out. Everyone fears the worst; Gordon the Blue Engine is gone forever. However, the Mallard comes up with a plan: he could tow Gordon out using a rope while on the quay Percy plunged into the sea from. Sir Topham Hatt says that it is far too dangerous as it may collapse under Gordon's weight. Mallard then suggests another engine should do it, but James and Duck do not say anything. Mallard points out this is the only way Gordon can be rescued. Sir Topham Hatt accepts, but says that if Mallard gets lost too, he will not be reliable. The plan is put into action, and Gordon is successfully salvaged from the ocean. The Fat Controller punishes Gordon severely. After the Mallard takes Gordon to the steamworks, the two make ammends for each other, and Gordon is certain he will never try to break a speed record again.
