The Sodor Warbler, a rare bird, has returned to the Island of Sodor, so the engines are taking visitors to see it. Henry's task is to collect the nesting pole and take it to Bluff's Cove. During his journey, Henry stops when he sees Thomas stopped to allow Farmer McColl and his sheep to go across the railway. Farmer McColl thanks Thomas for doing a good deed, which makes Henry want to do good deeds too.
Henry carries on up the line when he sees some pigs right by the track. He assumes the pigs want to get across the railway to play in the muddy field. So, Henry waits and then, the pigs go across the tracks and play in the muddy field, much to the annoyance of Farmer Trotter as he wanted his pigs to be clean for the county fair. Henry feels bad, and tries to make amends by reversing to allow the pigs some more space. However, his hissing causes the pigs to panic and spill crates of apples onto the track, just as Thomas arrives in the opposite direction with bird watchers aboard Annie and Clarabel. As the pigs are eating the apples, Thomas cannot move.
Henry decides to take the bird watchers for Thomas to Fenland Fields, where the Sodor Warbler has been seen. However, upon arrival at Fenland Field, Henry blows his whistle, scaring the Sodor Warbler so much that it flies away. This makes Henry feel worse than ever, as he still had not delivered the nesting pole to Bluff's Cove either.
On his way to Bluff's Cove, Henry sees a bird landing on his left buffer and gives it a ride to Bluff's Cove. To Henry's surprise, he brought the Sodor Warbler to the bird watchers at the station, who are very happy to see the rare bird. Thomas is pleased for Henry too, and Henry realises that he did a good deed without even knowing it.
Tropes featured in the episode:
- An Aesop: Your good deed might come out of nowhere, just be patient.
- Idiot Ball: Henry takes the visitors to the Fenland Fields where the warbler is located... then whistles a loud goodbye, which scares the warbler away.
- Rule of Three: Henry lets Farmer Trotter's pigs play in mud right when he was to take them to the county fair, his steam hissing scares the pigs and causes them to spill apples, and when he takes the visitors to the Fenland Fields, he accidentally scares away the Sodor Warbler with his whistling.
