The episode kicks off with Nathan Williams (portrayed by Martin Clunes) catching a glimpse of a badger family on his game camera, sparking his interest. He steps outside, intent on capturing them on film, but his focus is abruptly diverted by the sight of a drone hovering nearby. Curiosity piqued, Nathan trails the drone through the dense woods, eventually losing sight of it in an expansive, open field.
Shortly thereafter, Nathan encourages his son, Johnny Williams (played by Louis Ashbourne Serkis), albeit reluctantly, to accompany him for a test drive of a sleek new tractor. Johnny, though inexperienced, takes to the wheel with surprising ease, save for an abrupt, overenthusiastic application of the brakes. As they head back home, their journey takes them past The Palisades, prompting Johnny to mention his Uncle Caleb Williams (Mark Lewis Jones), who, according to Nathan's last knowledge, was employed there. Nathan offers Johnny the opportunity to lend a hand at Owen Thomas's (Michael Elwyn) farm, a proposition Johnny declines, citing homework obligations.
Meanwhile, Nathan assists Owen with a problematic tree branch, during which Owen reveals disconcerting news: an inconclusive tuberculosis test result from the vet. Furthermore, Owen floats the idea of selling the farm, a suggestion that falls flat with Nathan. To Nathan's delight, Owen's wife, Gwen Thomas (Sharon Morgan), treats him to a hearty meal of eggs and traditional Welsh cakes in gratitude for his help.
Upon returning home, Nathan finds Scott Foley (Michael Obiora) awaiting him, inquiring about renting the barn. Nathan informs Scott that the barn has been unrented for two years since the passing of his wife and directs him to The Skillet, a venue in town.
In the dead of night, Nathan was jolted awake by a phone call from Gwen. Rushing to her place, he discovered a harrowing scene: Owen, trapped in the barn, had a shotgun positioned under his chin, a dire situation that demanded immediate attention. Nathan exhausted every effort to persuade Owen to abandon his desperate act and gain entry into the barn before fate could be sealed by a tragic pull of the trigger. Alas, his interventions were in vain. In the aftermath, Nathan dialed for an ambulance for Gwen and a grim notification to the morgue for Owen.
Later that fateful day, Nathan sought out Pavel (portrayed by Marcin Zarczczny) to acquire materials necessary for extending the livestock fence. He also imparted the necessity of ordering another TB test. Upon completing the fence extension, Nathan's return to Thomas Farm was interrupted by a fleeting glimpse of someone peering through the window. Intrigued, he ventured inside and encountered Eva Bartosz (played by Natalia Kostrzewa), who introduced herself as the cleaning lady. Nathan's demeanor towards her was brusque, culminating in an abrupt dismissal after falsely accusing her of evading the police. This altercation caused him to be tardy for picking up Johnny.
On his way to fetch Johnny, Nathan's path crossed with Johnny and Rhys Simpson (embodied by Gerran Howell). Rhys, with gentlemanly manners, introduced himself to Nathan and offered Johnny a ride home on his scooter. Nathan harbored reservations but his thoughts were abruptly truncated by the recurrence of the menacing drone. Pursuing the drone once more, Nathan came within inches of apprehending its pilot.
Some time later, Nathan visited Gwen in the hospital, where she was consumed by grief over Owen's untimely decision to keep the farm's financial woes a secret. She entrusted Nathan with overseeing the farm in her absence, mentioning Eva's role in cleaning, assisting with the eggs, and feeding the hens. Gwen momentarily entertained the notion of selling the farm, a suggestion that now seemed sensible given the circumstances. Nathan, however, gently discouraged her from this course and vowed to handle the administrative responsibilities in the interim.
At Williams' farm, amidst the thrill of video games, Johnny found himself entangled in an unexpected errand when Rhys, his companion, entrusted him with a roughly wrapped package. Initially hesitant, Johnny's resolve strengthened upon learning of Rhys's recent burglary scare. Meanwhile, Nathan made a brief pit stop at the local pub before heading back to Johnny's place, where he ran into Gwen. He apologized profusely for his earlier rudeness, reassuring her about her job security and even inviting her to clean his home, promising payment on Friday.
That evening, over dinner, Nathan and Johnny's conversation veered towards Rhys and his brainy yet academically delayed sister, Sadie Simpson (portrayed by Carly-Sophia Davies). Johnny shared that Sadie's brilliance was marred by prolonged absences from school. He also speculated that Nathan might be contemplating the purchase of Thomas's farm, having caught a glimpse of its property line on a map.
Post-dinner, Johnny retreated to his room, where the allure of Rhys's mysterious package nearly overcame his caution, but ultimately, he refrained.
The following morning, as Nathan dropped Johnny off at school, Mrs. Roberts intercepted him for a chat. Meanwhile, at Thomas's farm, Eva accepted Nathan's earlier offer to tidy his house, unaware that Nathan's daughter, Claire, was currently in France, grieving her mother's passing, leaving just Nathan and Johnny in the household. Later, Nathan and Johnny encountered Scott, exchanging brief pleasantries before Nathan broached the topic of Mrs. Roberts's concerns about Johnny's recent demeanor and his abrupt cessation of swimming. Nathan persuaded Johnny to resume swimming and enforce a 9:00 pm video game curfew.
That night, while researching drones at home, Nathan received a call from Eva, who, on her way back from Thomas's farm, had witnessed three speeding cars racing towards the property. By the time Nathan arrived with his shotgun, the farmhouse was already pulsating with the energy of an uninvited gathering. With a single shot into the air and a declaration of impending police arrival, Nathan effortlessly dispersed the crowd. Stepping inside, he unexpectedly encountered Johnny.
Regardless of the peculiarities of the house's architecture, the beverage they shared, and the humble pot, Nathan treats Johnny with leniency. He even confides in Johnny about his arrest in Thailand, weaving tales from a bygone era. Their conversation veers briefly into more poignant territory, touching upon Nathan's father's passing and Uncle Caleb's storied service in the Marines. As Nathan tidies up, an offer from Black Mountain Estates catches his eye—a proposal to acquire the farm.
The subsequent day, Nathan seeks counsel from his bank manager concerning the potential purchase of Owen's farm. Despite the manager's cautionary advice, he assures Nathan of his eligibility for a loan to cover the deposit. At a cattle auction, fate places Nathan and Caleb in each other's company once more. Over frothy beers, Caleb attempts to draw Nathan into a discourse about Owen's demise, leveraging his own grim experiences with mortality from his Marine days. Nathan, however, remains steadfast in his silence.
Later, Nathan and Johnny encounter PC Jane Crowther (played by Eiry Thomas), who is busy confiscating illegally poached badgers staged to look like roadkill. Their conversation is cut short by the return of a drone, which Nathanthis time, opts not to pursue but instead inquires about its police affiliation.
Returning home, Nathan and Johnny find Eva has prepared a hearty Polish meal for them. Nathan invites her to join, but she politely declines, citing prior engagements. Johnny teases Nathan for his invitation, only to have his mirth diminish when he realizes the package entrusted to him has vanished. Amidst accusations that Eva might have pilfered some cash from his room, Johnny is interrupted by an agitated call from Rhys. Following the call, Johnny brushes it off as an overreaction and departs. Meanwhile, Johnny meets with Rhys to discuss the heist, while Nathan revisits Thomas's Farm and discovers a room adorned with mock alien artifacts.
Rhys manipulates Johnny into feeling guilty over the lost package, convincing him to deliver a backpack to a person named Dan (portrayed by Garmon Rhys) at Raglan Castle. The episode concludes on a tense note, with a policeman observing Johnny entering Raglan Castle, backpack in hand.
