Nearly a year has passed since the last season of Clarkson's Farm, with Clarkson getting the viewers up to speed on what has happened on the farm since then; changes at the farm include Clarkson having sold his sheep to "actual sheep farmer" Jeremy Sealy, the addition of durum wheat to his crops, "millions" more bees and the birth of Kaleb's son, Oscar. Clarkson also talks about the farm shop, which has turned out to be significantly more popular than they had expected, causing further jams and congestion; to alleviate this, Kaleb and Clarkson mow two acres of wheat to extend the carpark, but that too is insufficient. Clarkson then changes the topic, claiming that farm shop issues had to be dealt with by Lisa, as Clarkson was busy worrying about "a ticking timebomb" that would affect the farms within the United Kingdom.
It is now harvest time, with Clarkson hoping he can earn more than £144 worth of profit this year. To start, Clarkson and Kaleb perform a moisture test on the barley to see if it was suitable for harvest; it is, and Clarkson and Kaleb contact Simon, who arrives in a brand new combine harvester to aid in the harvesting. Midway through harvesting, Kaleb contacts Clarkson, stating that it is no longer conducive to harvest the barley; Clarkson then contacts Charlie for advice. Clarkson's fears are realized; all harvesting cannot go on and Clarkson and Kaleb have to begin unloading their barley.
Clarkson and Kaleb begin unloading their barley at their makeshift grain silo; Clarkson notes that vandals have attempted to set the silo on fire again, and that he contacted the police about it to try to solve this issue. Yet another problem was a shortage of truck drivers; due to this, Clarkson could only book one truck to take the barley away, with the rest left outside. With the next day's forecast being rain, the remaining 5 tons of barley would be ruined; Clarkson and Kaleb hope that the weather forecast would be wrong, but are dismayed to find out that it actually does rain.
Clarkson and Charlie are busy discussing why they had stopped yesterday, as well as talking about their lost profits as a result of drying charges and the unsold barley. However, according to Clarkson, this would be the least of his problems, as there was one giant issue that was on the back of every farmer's mind since June 2016: Brexit. This meant the loss of grants and subsidies from the European Union; despite the British government claiming that they would support the British farming industry, in Clarkson and Charlie's mind, as well as other farmers, these promises seemed insincere or unfulfilled. This is followed by a montage of various farmers voicing their concerns about this.
Charlie informs Clarkson that he will lose £82,000 worth of subsidies due to Brexit; Clarkson mentions that there were likely grants and subsidies, but there was no substance to those words, to which Charlie agrees. Clarkson then compares this entire situation to FIFA; Charlie agrees with the analogy. Clarkson, now fuming, tells Clarkson to spurn any comments made in the committee meetings set up by the government and comes up with a plan to aid him in earning additional profit: purchasing cows.
Opining that his foray into sheep farming was "a disaster", Clarkson explains to Charlie his rationale for purchasing cows, believing that it would be beneficial for the farm's ecosystem. Charlie asks Clarkson as to how many cows he wants to purchase, to which Clarkson cannot give a number; Charlie then warns Clarkson that the cows he wants to purchase run the risk of contracting bovine tuberculosis from the badgers living in the area, the area being considered "high-risk". Clarkson immediately suggests killing the badgers; this idea is shot down immediately by Charlie on account of it being illegal.
Clarkson then suggests a second plan to Charlie in an attempt to diversify; turning his now-unused lambing barn into a restaurant, using that as a medium to sell the beef from his cows along with other produce from the farm, the idea being that everything cooked or prepared at the restaurant came from the Diddly Squat farm. Charlie likes the idea but admits not knowing much about setting up a restaurant. Clarkson admits to Charlie that there is an 80% failure rate for restaurants, but that he has a plan for the restaurant to succeed: "be one of the 20%", and requests Charlie to find some cows.
While Charlie searches for cow farmers, Clarkson attempts to go back to harvesting but is thwarted yet again by rain, causing the crops to be too moist to harvest. Having rained for four days straight, Clarkson, thinking that the next day would be another unproductive day, proceeds to have the tires on his tractor changed. As he is getting his tires changed, Clarkson is confronted by an angry Kaleb, who questions why he is changing his tires now as the corn was ready for harvest. Noticing that Clarkson has to get out to do harvesting, the tire mechanics quickly change the rest of the tires and Clarkson heads out to begin harvesting.
Clarkson attempts to hitch up his trailer but runs into some issues; he calls a member of the film crew to spot to see if his hitch is working. By this time, Kaleb and Simon are getting impatient; as Clarkson finagles around to get his hitch working, Kaleb decides to go back and help Clarkson get his hitch working, and they proceed to begin harvesting. Clarkson and Kaleb work their usual shifts to get the barley unloaded; Clarkson later walks around the grain silo and notices a torn up Burberry shirt within the barley. He later notices that some of the barley had begun growing thanks to the constant rain, and thus cannot be sold; Clarkson is told by Kaleb to use a telehandler to spread out the barley so that future loads are dumped across the old barley, which will get mixed up in the truck and have the average turn out within the required limits.
Clarkson spreads the barley out, but is informed by a crew member that he should have removed the sprouted parts before mixing it up according to Kaleb, a fact which Clarkson denies. Kaleb soon arrives and commends Clarkson for his work, to which he celebrates. Simon, Clarkson and Kaleb manage to harvest all the barley and rapeseed over the next few days, before rain interrupts their harvest again; by then, Charlie has found cow farmers who were willing to sell Clarkson cows, and they drive over to see the cows. They arrive at the farm of Tim and Katy Coles, based in Northamptonshire. Clarkson and Charlie decide which cows to purchase; they decide to purchase some steers, heifers and calves and do some haggling for the pricing and agree to purchase the cows with calves for £2,000 each and the heifers for £1,450 each.
The wheat still is too wet to harvest the next morning, so Clarkson calls Alan over to discuss future plans for the farm shop and restaurant. Clarkson then discusses with Alan the price of building the restaurant, which comes up to at least £250,000. By this time, the wheat is dry enough to harvest, so Simon, Kaleb and Clarkson get back to work. As Simon is harvesting, Clarkson and Kaleb laugh about an anecdote relating to Simon. Back in the tractor, Clarkson and Kaleb continue joking about harvesting, with Clarkson later taking pot shots at Kaleb for describing his newborn son Oscar as "foreign"; Kaleb attempts to justify this by claiming that because Oscar was born in Oxford and not Chipping Norton he was therefore "foreign", while Clarkson cannot hold back his laughter.
Two days later, harvesting the wheat is nearly complete, with Gerald dropping by to finish off the harvesting. As Gerald drives Simon's combine harvester, it begins to beep at him; Gerald frantically communicates with Simon using walkie-talkies on how to fix the issue while Clarkson cannot hold back his laughter at the indistinct chatter between Simon, Kaleb and Gerald. Kaleb eventually rushes over to solve Gerald's issues with the combine harvester, and they resume with the harvest; they are done by evening.
The next day, Clarkson and Kaleb drive the Supacat to a field, which they begin fencing off for the cows. Not wanting to use Kaleb's "man-killer" fence post driver to put down 280 fence posts, he drives back with a SoloTrak fencing machine but doesn't know how to use it. Kaleb and Clarkson use the SoloTrak to complete the fencing work, as the machine also applies chicken wire and barbed wire to the fences. The fencing work is complete by the next day, when Clarkson's cows arrive; Kaleb cannot be present as he had to put down Diesel, his pet dog, so Charlie and Clarkson welcome the new cows to the farm.
