Peter The Postman has an eventful day as his deliveries cause a mixture of joy and chaos.

Windy Miller falls asleep. When he awakens, the sails of his windmill have stopped turning and he needs assistance to get them going again.

Mr Crockett attends to Mickey Murphy's delivery van which has broken down. Later, after visiting Mr Crockett's garage for a fill-up, Jonathan Bell the farmer challenges Windy Miller to a race.

Doctor Mopp visits patients all around the village, carries out a routine medical examination at Pippin Fort and even attends to a cow with a nasty cough. It's all in a day's work!

Farmer Bell is worried when his regular customers don't want his eggs anymore. A rival supplier has taken his business - but who is it?

Captain Snort sends his troops to help out the villagers with little tasks, but one of the soldiers goes missing.

Paddy Murphy works at the dairy, collecting supplies and making deliveries. But an accident causes the loss of a day's milk - who can he turn to for help?

When Roger Varley tries to clean up after sweeping the chimney at the bakery, he discovers that the water supply has been cut off. Fortunately, Windy Miller knows what to do - touch a sweep's collar for luck!

PC McGarry is trying to track down anyone fishing illegally when a call for help arrives - a swarm of bees has descnded upon the bakery! PC McGarry and the soldiers from Pippin Fort can't help, but they know a man who can.

Mr Dagenham visits one of his satified customers, Jonathan Bell the farmer, then goes to Pippin Fort to attempt to sell a helicopter. He doesn't sell it, but it comes in useful when Windy Miller needs to repair his mill.

Mr Carraway makes his deliveries to the mill and to Pippin Fort, telling stories of the sea to his customers.

Mr Murphy the baker burns his hands and can't bake his usual orders, so Private Lumley is sent in from Pippin Fort to help. Unfortunately Lumley isn't the brightest of the soldiers and chaos ensues.

Village gossip Mrs Honeyman jumps to the wrong conclusion when she sees workmen arrive in Camberwick Green, and organises a protest against the green being dug up.

The Trumpton fire brigade attempt to put up posters to advertise their band concert. But there doesn't seem to be anywhere they can put them, and when they do get to put some up, they get in an awful mess.

The Mayor of Trumpton inspects the town park. He discovers a broken bench, which is soon mended, but then a gust of wind blows his hat off and the Fire Brigade are called in to retrieve it from a tall tree.

Mrs Cobbit has a very bad day - first the branch of a tree crashes through her roof, then when she gets to the town market, she finds that an ice-cream man has taken her regular pitch. Fortunately with the help of the other townsfolk, her problems are soon solved.

A sticky door sets off a chain of events which results in the town-square statue of Queen Victoria being damaged. Fortunately the fire brigade are on hand to put matters right.

The face of the town clock needs repainting, but of course nothing ever goes smoothly in Trumpton and a misplaced pot of paint causes havoc.

The Mayor is very proud of his position and would like a painting of the Town Hall. The villagers decide to give him the painting for his birthday, and Chippy Minton has seen an artist painting scenes in the village. But the artist has vanished, so Chippy and the other villagers go looking for him.

The Mayor calls in an engineer to sort out a problem with his phone. The engineer digs down to the telephone wires, but when he goes to lunch, one of Mrs Lovelace's dogs falls in the hole and discnnects all the cables! The assistant, Fred, tries to reconnect the wires but gets it all wrong and much confusion ensues.

Raggy Dan, the rag and bone man, collects old junk from the townsfolk, but Mrs Minton doesn't realise that the old rocking horse she gives him has Chippy's savings hidden inside.

Mr Robinson the window cleaner, gets stuck on a roof, and the fire brigade are called in to get him down.

Fireman Cuthbert has a morning off and goes to visit his aunt. But the two of them get separated in town and end up looking for each other. Even the rest of the fire brigade get involved in the search.

While doing repairs in the town hall, Chippy Minton and his assistant Nibbs discover that the water tank is leaking, and they call in the plumber, Mr Wilkins. He sees that the tank needs replacing, but he finds that he can't remove the old one, so the fire brigade are called in to help.

Chippy Minton can't get to Trumpton because of a fallen tree blocking the road. Luckily he is able to summon help by messenger pigeon.

A fruit and veg show is due to take place in the park, but then the old greenhouse chimney is declared unsafe. Once again, it's the Trumpton fire brigade to the rescue.

Dr Mopp calls at the Chigley Pottery to buy a vase for his sister Millicent, and gets a demonstration of how a potter uses his wheel. Lord Belborough arrives in Bessie to collect a crate of pottery, and they go with him to Treddles wharf, where he picks up a mysterious crate. Dr. Mopp asks the Camberwick Green villagers if they know what is inside the crate. Mrs Honeyman suggests that it must be something to do with the six o'clock whistle at the biscuit factory, which proves to be correct. At 6.00 the workers leave the factory and Lord Belborough unveils to them a Dutch organ which plays the music for the six o'-clock dance.

Farmer Bell makes his regular delivery of produce to the Chigley biscuit factory, and gets a tour of the factory from Mr Cresswell. They notice that a box of biscuits meant for delivery has been overlooked. As Trumpton is very congested at this time of day it is too late to take it by road to Wintelbury station, in time for the 5.23 train to London. Farmer Bell comes to the rescue by taking the box to the pottery where it is picked up by Lord Belborough in Bessie and taken to Treddles Wharf. Here it is transferred to Chippy Minton's truck which he drives off to Wintelbury. Mr Swallow then points out that as the timetable has recently been changed, the train doesn't leave until 5.43, and so they would have made it by road anyway!

The Mayor of Trumpton visits Lord Belborough and asks him for fund-raising ideas for the Old People's Holiday Fund. When Lord Belborough has to go to the Pottery he gives Winnie a ride on Bessie. Her balloon gives him an idea.

PC McGarry calls at the pottery to invite Mr Farthing to tea. Mr Farthing is sculpting in his garden but explains that there is not much demand for stone sculptures these days. PC McGarry then calls in at the Biscuit Factory where he tells Mr Cresswell that he has a clean and modern looking factory, but also points out that a fountain would look nice. Mr Cresswell asks Mr Farthing the Potter to make one. Lord Belborough picks up the block of stone from Treddles Wharf, Farmer Bell digs the foundations and Mr Clutterbuck builds the fountain's basin. Then at six o'clock one evening, when it is all finished, the Mayor of Trumpton unveils the fountain.

Mr Crockett delivers a lawnmower to Winkstead Hall, having just rebuilt the engine, and "sharpened her up". Lord Belborough starts the mower, which was still in gear, and it runs off and demolishes the garden wall and door. Lord Belborough phones Mr Clutterbuck the builder and asks him if he can rebuild the wall before the weekend, but Mr Clutterbuck is still awaiting delivery of a load of bricks, which are stuck at Treddles Wharf. Lord Belborough and Brackett steam of to the wharf in Bessie and collect the bricks. Bricklayers Cyril and Horrace are then able to rebuild the wall, while Chippy Minton and Nibbs make a new door. Mr Crockett repairs the mower, "using several completely new parts" and everything is ready in time for the six o'clock dance.

Roger Varley arrives at Winkstead Hall to help clean Bessie the steam engine and Binnie the pumping engine. Roger is cleaning Binnie when Brackett the butler comes in and says the water level in Winkstead Hall is very low. But the only way to pump the water is to burn the coal to get the pumping engine going, but there is no coal left. They ring up Mr Swallow at Treddles Wharf and ask for some coal. He tells them that they will have to pick it up. They set off in Bessie, pick up the coal at the wharf, and return to Winkstead Hall. With a new delivery of coal Binnie can pump again. The biscuit factory whistle blows and it is time for the six o'clock dance.

Thomas Tripp is delivering milk to Winkstead Hall, and while talking to Brackett they discover that because Lord Belborough's birthday is in February then today is his lucky day. Later, Lord Belborough is telling Brackett about his antique vase, (and that he is looking for another to make a pair) when he accidentally drops it, smashing it into pieces. When the dustmen arrive they empty the Winkstead Hall bins and take away the vase fragments.

Mr Carraway is delivering three boxes of plaice to the Chigley biscuit factory restaurant when PC McGarry turns up and tells them that the Chigley bridge is unsafe and closed to all traffic. This is bad news for Mr Cresswell as he has a delivery of biscuits to go out. Mr Carraway points out that the boys from Pippin Fort have a temporary bridge but it is kept at Treddles Wharf, which is on the other side of the river. A few phone calls later and Lord Belborough goes off in Bessie to collect it from the wharf and take it to the bridge. Unfortunately the soldier boys are still on the wrong side of the river, but with the help of Mr Dagenham and his helicopter they are picked up by rope, three at a time, and carried across the river to where they can assemble their temporary bridge. Mr Carraway has the dubious honour of being first to try out the bridge, and then they all go off to the six o'clock dance.

Mr Wantage and Fred finish their work in Trumpton and go off to the Chigley pottery to mend Harry Farthing's phone. There, they find that the trouble is due to clay in the receiver holder. Harry gives them a demonstration of how he makes a bowl. The PO engineers mention that a lot of clay was dug out when the new telephone exchange was built, and they give Harry a lift to the exchange in their van. They tell Harry he can have it all, but how can they transport it back to the pottery?

At Treddle's Wharf, Mr Rumpling is supposed to unload a crate from his boat for Lord Belborough, and pick up a crate of scrap metal from Farmer Bell. While lifting a crate the crane fails and drops what they think is Lord Belborough's crate of valuable antique books into the canal. The solider boys are called and Private Armitage (the best swimmer) dives into the canal to rescue the crate. However due to a previous mix-up, the dropped crate is found to contain Farmer Bell's scrap metal, which obviously isn't damaged by having been dropped in the canal.

When the Winkstead orchard has a bumper crop of apples, Windy Miller suggests they turn them into apple juice using his cider press. The fire brigade pick the apples and Jonathan Bell loads them onto Bessie with the aid of his forklift loader. Then Lord Belborough takes them to Windy's barn (just below the mill) and with the help of the biscuit factory workers they are pressed and barrelled in time to be taken to the six o'-clock dance.

Mr Clamp takes some stock to the Chigley biscuit factory for the staff canteen. While there, he asks Mr Cresswell (the biscuit factory owner) how his nephew Willie Munn is doing. Mr Cresswell takes Mr Clamp to see Willie who works on the biscuit stamper.

Mr Antonio is delivering ice cream to the Winkstead Hall tea room. He meets Mr Bilton the gardener, who says he has some wall flowers to give him. Mr Bilton is suffering from 'the rheumatics' so Mr Antonio helps out by doing a bit of lawn mowing. On his way out Mr Antonio meets Lord Belborough who tells him he would like to give Bilton a motor-barrow but can't afford it what with the cost of the recent reroofing...
