Opening to a shot of two eagles flying over the farm, Clarkson immediately hammers home the point of Gerald's cancer diagnosis; Kaleb and Clarkson then attempt to mend the dry stone walls with the thought weighing on their minds and both discussing it at length. As they continue discussing, Clarkson and Kaleb appreciate the work that the now-74-year old Gerald has done for them all this time before cutting to the intro.
Now in late fall, Kaleb discovers that the rapeseed fields he attempted to plant despite Clarkson and Charlie's dissuasions had failed, to which he sighs in exasperation. Kaleb drives over to Clarkson and is even more exasperated to find an unfamiliar tractor on his fields; it turns out that the individual in the tractor is British musician Andy Cato of electronic music duo Groove Armada, who had dropped by the farm a few weeks ago along with his business partner, former television presenter George Lamb, to discuss regenerative farming with Clarkson and Charlie; a flashback occurs to the event, where Andy, Clarkson, Charlie and George as shown discussing the matter at length, with Clarkson and Charlie ultimately agreeing to the deals and conditions set by Andy and George.
Back in the present day, an extremely exasperated Kaleb is none too pleased to see Andy drilling his field, while also claiming that the method that regenerative farming method Andy would be using would not work. Soon after, Kaleb and Andy meet for the first time, with Andy talking to Kaleb about his farming methods and the deal struck between Diddly Squat, him and Charlie. Now in November, Clarkson was now reading up material preparing for the impending arrival of his Oxford Sandy and Black pigs; he and Lisa would then proceed to build the pig pens in the potato fields, with Kaleb absent due to having taken ill. As they prepare to build the pens, Clarkson talks to Lisa about his rationale for getting the pigs and the story behind the pigs and use a JCB telehandler and Clarkson's Lamborghini tractor to transport the materials.
Clarkson and Lisa begin the building through the fence posts used to create the enclosure, with Clarkson having borrowed a hydraulic post driver from Kaleb to knock the fence posts in; they work into the evening, in the rain and weather battering down on them. Two days later, they begin assembling the fence, with Clarkson pulling wire mesh around the fence posts to finish up the enclosure; naturally, Clarkson manages to pull down one of the fence posts he was tensioning using the wire mesh, causing more issues and annoying Lisa. Both would assemble the gate to the fence afterwards, albeit improperly and have to restart; following this, Lisa and Clarkson assemble an ark for the pigs.
Despite the pens not being fully complete, the pigs arrive with their handlers Peter Colson and Josh Farrell of the Oxford Sandy & Black Pig Society, who guide the pigs into their pens. After observing a number of pigs fighting, they put the piglets in their pens while Lisa fawns over them. The final group of three pigs would then be released into a separate pen where they would be breeding; these consist of a sow named Mabel, a gilt named Sarah and a boar named Ajax. After the pigs are released, Lisa and Clarkson resume working on building the pigs's arks, ideally to have them completed before nightfall. With the pens set up, Lisa readies up the pens for Mabel, Sarah and Ajax with hay; she is soon after smothered by the threesome in the ark, while Clarkson looks on and cackles gleefully.
With the pigs having settled into their pens, Clarkson has a meeting with Charlie about various matters. After "waking up two days later", Clarkson goes about loading a grain truck on his own, with Kaleb still down with sickness; one run has him miss the truck entirely and dump a pile of grain beside the truck, to which Clarkson requests the Amazon film crew to "edit that out". Some time after, Clarkson and Lisa drive down to the pig pens, where they discuss Ajax's issues with coitus; they later observe Ajax trying to mount Mabel with no success, leading to Mabel being electrocuted by the electric fence. Clarkson and Lisa decide to leave Ajax in the pen for a week and hope for better luck afterwards.
Soon after, Jeremy Sealy, a neighboring farmer, arrives at Clarkson's compound, where he releases the sheep Clarkson had originally bought in Season 1 back into the fields; Lisa joins afterwards and all three converse, with Lisa congratulating Jeremy on his marriage. Clarkson and Lisa soon after prepare the winter barn for the cows, while Clarkson complains about Kaleb's absence, he having fully recovered and is now on vacation in Cornwall. They complete the pen and lead the cows in, with Clarkson commenting that one of the cows "looks delicious".
Having assumed that Ajax had "done his thing" in the initial pen, Clarkson and Lisa were set to move Ajax to a second pen in an attempt to successfully breed some piglets; confusion ensues with an improperly assembled fence gate that is somehow connected to the electric fence, the worsening weather and one of the gilts escaping into the wrong pen while Clarkson was not paying attention. While doing this, Ajax tries to mount the gilt, causing one of the sows to become a little bit "jealous" and more aggressive towards Ajax; Lisa attempts to pretend that something was indeed mounting the sow while they left Ajax to his devices. This is to no avail, so Clarkson decides to distract the sow "with something better than sex": ginger snaps.
With Clarkson being told to get ginger snaps, much to his confusion, he observes Ajax successfully mounting the aforementioned gilt; Lisa eventually assigns Clarkson to "mount" the sow while she goes and get ginger snaps to feed the sow. After a very long act of coitus, Ajax dismounts the gilt and all the pigs are moved back to their pens. With this complete, Clarkson starts to relax, only to find a mysterious brown liquid in this coat pocket; he surmises that "one of the pig's been sick in his pocket".
Two months have passed since Andy drilled Kaleb's field with beans and wheat, with Clarkson and Charlie checking up on the progress of the crops; delighted, they find out it indeed has worked, proving Kaleb's initial theory wrong. While in the field, Charlie gives Clarkson a crash course on the benefits of Andy's method of regenerative planting. Following this, Clarkson and Charlie discuss about the enforcement notice he was served by the council regarding the restaurant and the farm shop; Clarkson recognizes that he could not see a viable way to reopen his restaurant but something had to be done to save his shop. Clarkson suggests the farm shop be moved out of Chadlington's parish district so it would not be under their jurisdiction, but Charlie disagrees and suggests that instead the location of the farm shop should remain as is and that they hire a legal team and put together a response to challenge the council's views, a move Clarkson agrees with.
With Charlie back at his office to start work on his appeal, Clarkson and Lisa return to the pig pens to get some work done; this is stalled with Clarkson's Range Rover being stuck in the mud with no way of getting out on its own. As the Range Rover tries to free itself from the mud, the piglets scurry out of their ark to see the happenings, to which Clarkson and Lisa laugh; Clarkson decides to pull the car out with a tractor. Bringing his Lamborghini tractor to free his Range Rover, Kaleb returns from his vacation and is greeted by Clarkson and Lisa. Kaleb is shocked at seeing the pig pens in his potato fields, wondering who built them; on discovering that Clarkson and Lisa built them, Kaleb begins nitpicking at all the various flaws the pig pens have, with Lisa defending her design decisions.
Clarkson shortly after describes how his system of pig pens work and that he got the pigs successfully impregnated within a span of two weeks; this amuses Kaleb to no end, who tells Clarkson that he is likely going to end up with a litter of at least fifty piglets running around the pen as he did not spread it out. Clarkson looks at the camera with an annoyed look on his face.
