Plot: Flynn is sad after he causes himself an accident but when Thomas, Percy and Belle are stuck in a fire, it's up to him to rescue them in time for May Day.

It was May Day on the Island of Sodor.

All of the engines were excited.

It was their day off today and a party was going to be hosted at Knapford Station.

That afternoon, Sir Topham Hatt arrived at The Search And Rescue Center.

"Belle and Flynn," he announced, "I have a few jobs for you to prepare for the party tonight since my engines are taking their day off. First, you must pick the banner and decorations from Brendam Docks. Then, you are to pick up a cake from the bakery and bring it to Knapford Station. Then you must pick the passengers from Maron Station and bring to them to the party."

"Yes, sir," said Belle.

"Right away, sir," said Flynn.

And he raced off.

Belle chuffed after him.

"Whoa, Flynn," she called, "wait up."

But Flynn was in too much of a hurry.

He raced along the line chanting "I'm a hard working fire engine for more jobs then a few. If there's ever any trouble, I'll race to the rescue."

Soon Belle and Flynn arrived at Brendam Docks.

Salty, Harvery and Murdoch were there as well as Diesel, Den and Dart.

"Well if it isn't Foolish Flynn," said Diesel.

And the three of them laughed.

"Be quiet!" wheeshed Belle and sprayed water right into their faces.

The diesels were cross but Flynn was more determined then ever.

"That load is very heavy," said Murdoch, "Belle and Flynn, you must haul it together."

But Flynn wasn't listening.

"Here I come," he chanted and raced into the cars of decorations, pushing them off the track.

Flynn was derailed as well.

"Flynn," gasped Belle and raced beside him, "Flynn, are you alright?"

"Engine overboard," said Flynn slowly.

And the diesels laughed and laughed.

Sir Topham Hatt arrived at the docks.

He was cross.

"Flynn! Look what you've done! You've biffed and bashed the cars off the rails and now Harvey will have to clear up the mess. Then Belle must take the load herself."

"Sorry, sir."

"It's off to the Steamworks for you now, Flynn. Hopefully you can be mended in time for tonight."

"Yes, sir."

Soon, Harvey lifted the cars back onto the rails and Thomas arrived to help Belle haul the load of decorations to Knapford Station.

"Oh, dear," thought Flynn sadly, "I probably won't make it tonight."

Nevertheless, Percy bought Rocky along and Rocky lifted Flynn onto his flatbed.

"Percy and Rocky then bought Flynn to the Steamworks where the workmen set to work set to work at mending him.

Flynn sighed sadly.

"I'm sorry if I caused you all this extra work, Victor. I should've never been so silly."

"That's alright, my friend. These men will have you fixed in no time."

That made Flynn feel a bit better.

Meanwhile, Thomas and Belle delivered the banner and decorations to Knapford Station and picked up the cake from the bakery. Finally, they puffed into Maron Station with Annie and Clarabel.

Lots of passengers were waiting.

"All aboard!" said Thomas.

And he whistled happily.

Belle rang her bell after him.

The passengers boarded Annie and Clarabel and the two engines chuffed away.

Thomas and Belle met Percy by the Dieselworks.

"Hello, Percy," they said.

"Hello, Thomas. Hello, Belle. Where are those passengers going?"

"To the party of course," said Thomas.

"It's going to be the best May Day party ever," said Belle.

Then there was trouble.

Paxton accidentally pushed some cars into a water tower, knocking it over.

"Uh-oh!" he gasped.

Norman and Dennis whooshed out of the Dieselworks, acting rather carelessly. They were racing to see who was faster.

"I'm fastest in the Dieselworks," boasted Norman.

"No. I'm the fastest in the Dieselworks," boasted Dennis who puffed onto Norman's line.

The two diesels accidentally biffed some fuel wagons off the tracks while fuel leaked out while the collapsing water tower crashed over it.

Water dripped into the fuel, causing a fire to erupt.

"Oh, no!" gasped Percy.

"I'll stop the fire," said Belle.

And she tried to but her hose tanks were empty.

"L-l-let's get outta here, Dennis."

"R-r-right away, Norm."

And the two of them puffed quickly away back to the Dieselworks.

Thomas, Percy and Belle tried to escape but fire roared across the tracks and across other side of the tracks as well.

The three engines were trapped.

"HELLLLLLP!" they wailed.

The diesels had left for the party so no one was there to help them.

Flynn was soon mended and raced into the Search And Rescue Center to hear the alarm.

Workmen came running from fire station.

"Fire! Fire!"

Harold came hovering into the air.

"Mayday! Mayday! Tank engines in trouble!"

Flynn was puzzled.

"What is this all about?" he asked Rocky.

"Must be about a fire."

"A fire!" gasped Flynn.

"Thomas, Percy and Belle are in trouble!" said Captain.

And he honked his horn loudly.

Flynn was startled.

"Thomas, Percy and Belle? In trouble? I'm on my way!"

And he raced off before the workmen could board him.

Flynn raced along the tracks chanting "I'm a hard working fire engine for more jobs then a few. If there's ever any trouble, I'll race to the rescue."

He soon arrived beside the Dieselworks in front of the fire.

"Thomas! Percy! Belle!"

"Flynn!" they called back, "help us!"

The three engines never looked so scared.

Flynn slowly put his hose tanks in position. Then he pumped his pistons and bravely sprayed water out all over the fire, stopping it.

The engines were saved.

Flynn's hose tanks were empty and he did feel a bit foolish for leaving the Search And Rescue Center without the workmen.

Sir Topham Hatt arrived.

Flynn was worried that he would be cross with him but he looked very pleased.

"Well done, Flynn. You have saved Thomas, Percy and Belle from a nasty fire. You, Flynn, are a really useful fire engine."

"Thank you, sir," said Flynn.

He didn't feel silly anymore. He felt very pleased with himself.

Soon, the four engines left the Dieselworks and chuffed along the tracks.

Flynn chanted "I'm a hard working fire engine for more jobs then a few. I saved my friends from trouble because I raced to the rescue."

Flynn, Belle, Thomas and Percy arrived at Knapford where they dropped the passengers off.

The children cheered when they saw Flynn.

"Hooray for Flynn!" they chanted.

Flynn felt very happy.

That night, the party was a great success.

Children clapped and cheered.

The band played and Belle congratulated Flynn.

"Thanks for helping me, Flynn. You are a really brave fire engine after all."

"Thank you, Belle. If there's anything I like better then being bold, it's helping out a friend in need."

All the engines cheered and whistled.

Especially Flynn who was the happiest of all.
