Pat and his black-and-white cat Jess deliver the mail in Greendale.
Pat calls to the Post Office and today most of the post is for Katy and Tom because it their birthday. Pat goes to deliver the post to them. Poor Katy is not having a happy birthday because she has lost Sarah-Ann, her doll that she takes everywhere. Pat's round then becomes a search for the missing doll. He comes across a load of other things but not the doll. Will he find Katy's missing doll in order to save the day?
Pat stops for a picnic lunch near Thompson Ground halfway through his round. He falls asleep in the warm sunshine. Some hens cause mischief, one takes Pat's sandwiches and the other takes Pat's keys! The hen surprisingly leaves Pat's keys in a nest in a tree. Dorothy soon comes to see what the commotion is about. Pat and Dorothy then go to get a ladder and Pat climbs up the tree to find a magpie's nest with some other missing things. Who has ever heard of a magpie hen?
Pat always thought he had managed to keep the date of his birthday to himself. He tells Jess not to give his secret away. When he arrives at the Post Office, all of the post is for Pat. As he then goes on his round, everyone he meets knows it's his birthday! How did all those people know?
It has been raining very heavily in Greendale. Even the letters are wet when Pat goes to the Post Office to collect them. Later Pat is stopped when a road has to be cleared of a blockage of mud. Bill brings his model plane and Pat ties an SOS message to it and flies it over to Peter, giving him the message to clear the blockage with his tractor and bulldozer plough.
Pat is having a late day after his van gets stuck in the mud. When he arrives at the Post Office, Mrs Goggins shows him a newspaper article about Major Forbes' bull. Later Ted stops Pat and they have to get some sheep out of a field filled with clovers. Later Ted thinks he's broken his ankle so Pat goes to fetch Dr Gilbertson from the village.
Pat has to deliver some eggs and a registered letter to some campers. The letter is too valuble to leave and the campers are at the waterfall. Pat's van can't travel the bumpy road so Miss Hubbard borrows a tractor and takes him on a rather bumpy ride to the waterfall. When Pat returns to his van, he sees that a hen has got in and laid an egg!
All of Greendale's water supply has had to be turned off. When Pat arrives at the Post Office, Mrs Goggins gives him some lemonade to quench his thirst. Later Granny Dryden shows Pat an old water pump in the village. Can Ted fix it in order to get a water supply working?
Pat finds it hard to steer his van in such a big wind. A fallen tree blocks the road and Peter goes to borrow a chainsaw from the forestry commision to cut the tree up. When Pat can get on his way again, his van's engine jerks. Pat gets out to have a look at it and the wind blows his hat off and it ends up in a lake!
There is a thick fog in Greendale. Pat feels foolish when he thinks a scarecrow is Ted and gives him a letter. When Pat calls at the church, Jess gets out the van. Pat soon finds him but they end up completely lost in the fog. When Miss Hubbard arrives at the church to see the Reverend Timms, she suggests that they ring the church bells to guide Pat and Jess back to the church.
Pat's alarm-clock fails to wake him up. Miss Hubbard passing by outside rings her bicycle bell to wake him up. Pat has to rush out to work in a hurry! When he calls at the Post Office, Mrs Goggins has a parcel of some spare parts for Ted and it just falls to bits. Poor Pat just ends up having a day full of disasters where one thing after another goes wrong!
Heavy snow has fallen in Greendale and Peter has to clear the roads with his tractor and bulldozer blade. When Pat calls to see Mrs Pottage, everyone has to help dig the snow away but it eventually becomes so bad that Peter has to turn back. When Pat arrives at Thompson Ground, Pat and Alf go on a sledge to deliver a parcel and some groceries to George at Hill Top Farm.
Another snowfall has fallen in Greendale. Ted lends Pat some old skates that belonged to Bert in Australia. When the road is blocked, Pat has to skate over the ice to deliver the post. He finds it difficult to skate on the ice though!
Pat calls to collect an Australian stamp from the Reverend Timms, who will be visitng London to meet his sister Elsie from Australia. When Pat arrives at the Post Office, Elsie phones Mrs Goggins to say she will come straight to Greendale because her flight is diverted to Manchester. Will Pat be able to stop the Reverend from catching the train to London?
