Yai Boon Kub Mor Tuem

Touchma or Tuem, a handsome young veterinarian from Kasetsart University, is happily taking graduation photos with his friends. In stark contrast, his father, Kamnan Ther (Village Headman Ther), feels humiliated and furious. The Headman had been bragging to the entire sub-district that his son was studying to be a medical doctor who treats humans, only to find out he studied to treat animals. Paramee or Lookpla, Touchma’s younger sister who is in her final year of Home Economics, has to calm her father down. Although Kamnan Ther doesn't like her major either, he eventually gives in to her pleading. Touchma returns home, where he is looked after by Paen Lan, an older transgender maid of the Kamnan’s household who constantly flirts with him, though Touchma is used to it and remains unfazed.
Kamnan Ther returns from the temple feeling ashamed because people were laughing at him. Angry that Touchma doesn't appreciate his good intentions—having raised his children alone since his wife died and planning their paths for them—Kamnan decides to teach Touchma a lesson. He goes to Satan Suang Farm in Saraburi to ask Boonjira or Mae Boon, the farm owner, to hire Touchma. Kamnan is a distant relative of Boonjira's mother and worked on the farm during its pioneering days. Although Boonjira's parents have passed away, she respects Kamnan like a close relative and agrees. Kamnan returns and forces Touchma to work as a cowboy at the farm, claiming Touchma must work to repay the money spent on his education. Paen Lan wants to go too, but Kamnan forbids it.
Kamnan has Ai Jook, a driver he once helped, take Touchma to the farm. Since the pickup truck is unavailable, Jook drives him in an E-taen (local farm truck) instead. On the way, Touchma imagines Boonjira as a fussy old spinster. However, upon meeting her, he is stunned because Boonjira is young and beautiful, despite being a widow with three children. Seeing that the children look completely different from one another, Touchma assumes she must have had husbands of various nationalities. Satan Suang Farm is vast, featuring a dairy farm, horse stables, a breeding center for high-quality cattle, and modern agricultural plots. Boonjira assigns Touchma to the dairy farm on a probationary basis and warns him to strictly follow the farm's rules.
On his first morning, Touchma faces a hazing ritual from Boonjira's adopted children: Tommy (the eldest, of German descent), Congo (the second son, of Kenyan descent), and Lookmee (the youngest daughter, of Korean descent). The three lead the workers' children, dressed as a Native American army, to attack Touchma. Orachorn, the maid of the main house, tells him that if he were a woman, the hazing would have been a ghost prank instead.
In the workers' quarters of the farm, there is a single shop owned by Nang Peep, the wife of Ta Parn, an old farmhand. The couple fights every morning, especially when Ta Parn is drunk, as he accuses every man of flirting with his wife. That morning, Touchma tries to buy a toothbrush but is chased away by Ta Parn, who accuses him of being his wife's lover.
Meanwhile, Songsak or Sia Song, a rich young man and son of a wealthy agricultural warehouse owner, comes to court Boonjira, bringing gifts every time. The children hate Songsak because they are possessive of their mother and because Songsak is stingy and likes to oppress those weaker than him. The kids call him "Tee Saeb" behind his back. While he talks to Boonjira, the kids shoot him with a slingshot, causing him to fall. Touchma meets a sober Ta Parn at the farm, who doesn't remember him and politely shows him around, explaining that Boonjira doesn't raise beef cattle because she is too kind-hearted to send them to the slaughterhouse. This impresses Touchma. In the evening, the kids ambush Touchma, but he dodges them. He lectures them, annoying the kids further. Touchma learns from Ta Parn that the kids test everyone to ensure their mother isn't harmed or deceived, though Touchma disagrees with their methods.
Songsak drives recklessly to see Boonjira, nearly hitting Touchma and knocking him into a ditch without apologizing. Touchma retaliates with stinging words. The kids plan a ghost prank for Touchma but test it on Songsak first, scaring him so badly he drives his car onto a fence and loses his hair from shock. Pleased, they try the plan on Touchma, but he outsmarts them. However, the kids eventually cause Touchma to fall off a ladder and break his leg. He is hospitalized. Boonjira apologizes but points out that Touchma provoked the children first.
Paen Lan and Paramee miss Touchma and ask to visit him, warning Kamnan that Touchma might run away with a wife if they don't go. Kamnan agrees. Boonjira welcomes them warmly as she has known Paramee since she was a child, allowing them to stay as long as they like. When Touchma is discharged, he drags his cast-bound leg to Nang Peep’s shop. A drunk Ta Parn chases him with a knife again. Touchma runs for his life, which miraculously heals his leg overnight, allowing him to return to work.
The workers prepare the stables for an injured horse from Kirkpol’s stable in Korat. Kirkpol is an influential figure in horse gambling circles. Boonjira runs a nursing center for horses, and Kirkpol sends Det Duang Daraka, a champion horse who is severely injured. If the horse doesn't recover, it will be "put down with dignity." Touchma disagrees with this practice.
Kirkpol arrives by private helicopter with a plan to monopolize the horse racing industry and invites Boonjira to partner with him. She refuses, but Kirkpol plans to take over her farm eventually. The kids hate Kirkpol but don't know how to handle him. Touchma bonds with Det Duang Daraka until the horse trusts him, but the horse panics upon seeing Kirkpol. Kirkpol orders the horse to be found and killed. Touchma suspects animal abuse, but Boonjira is skeptical.
Songsak mocks the children, leading them to beat him up. Paramee prepares to leave, but Boonjira invites her to intern as an admin officer, delighting Paen Lan. Touchma finds the runaway horse in the forest, calms it down, and secretly treats it. The kids prank Songsak with itching powder, then hide in the stables. They see Touchma riding a horse skillfully, making Lookmee jealous. Boonjira is angry when she learns Touchma hid the horse, but he asks for time to prove the truth. The kids, learning the horse is to be killed, decide to help Touchma protect it.
Touchma bargains with the kids: they must follow his orders to help care for the horse. Boonjira stalls Kirkpol by ignoring his calls and goes to adopt Mali, a sickly baby, as another child. Touchma discovers that the horse has been doped with dangerous stimulants, causing bone decay. When Kirkpol returns, Touchma hides the horse at Ta Parn’s house. The kids attack Kirkpol’s helicopter with clay bullets, causing it to crash. Kirkpol calls the police with sniffer dogs, but Touchma uses fermented fish (Pla Ra) to hide their scent, saving the kids from arrest.
Touchma moves the horse to a limestone cave in the forest. The kids trick Songsak into letting them wash his car, which Touchma uses to transport the horse, returning the car in a ruined state. The kids promise to keep the secret.
Frustrated, Kirkpol calls Taweephol, a henchman who fled to the US, to infiltrate the farm as a stable hand to kill the horse. Touchma contacts a reporter friend to dig up dirt on Kirkpol, finding evidence of his gambling empire ruining lives.
The kids catch Taweephol in a trap, but he charms them by playing a cool cowboy named "Nickie," and they accept him. Mali falls ill with dengue fever, and Touchma donates blood to save her, touching Boonjira’s heart. Taweephol flirts with Paramee to get information. Boonjira dislikes Taweephol’s reckless behavior but keeps him on. Touchma finds proof of the intent to kill the horse but waits to tell Boonjira. Meanwhile, Taweephol turns the kids against Touchma, encouraging a violent cowboy lifestyle.
Boonjira, unhappy with Taweephol’s influence on the children, assigns him to work under Touchma shoveling manure. Touchma disciplines the kids by making them work and eat with the laborers. Taweephol tries to find the horse but is thwarted by Ta Parn, who knocks him out in a jealous rage.
Lookmee becomes disillusioned with Taweephol’s weakness. The siblings fight, and Boonjira is stressed. Touchma comforts her, and she decides to give Lookmee a foal, asking Touchma to train her. Taweephol finds the horse’s hiding spot. Kirkpol orders him to kill the horse and Touchma before the next race.
Kirkpol organizes a launch event for a new horse at Satan Suang Farm. Touchma plans to expose him. The kids fight, and Lookmee runs away to the horse. Taweephol attempts to kill both the horse and Lookmee, but Touchma and Ta Parn save them. The kids reconcile and reveal Taweephol’s true nature. Taweephol kidnaps Paramee into the forest. A rescue mission ensues, involving smoke tactics that backfire, leading to Touchma’s capture.
Boonjira asks Det Duang Daraka to help find the group. The horse leads them into the forest. Taweephol mocks the children’s orphan status, making Touchma sympathize with them. The horse attacks Taweephol, saving everyone. Taweephol is locked up.
At the event, Kirkpol tricks Songsak’s father. Kamnan Ther arrives and accidentally frees Taweephol before being captured himself. During the charity race, the kids set off firecrackers, causing chaos. Det Duang Daraka appears, and the kids expose Kirkpol’s crimes. A gunfight breaks out. Touchma protects Boonjira, and the horse protects Touchma, getting shot in the process. Police arrest the villains. Touchma saves the horse's life. He promises to help restore the farm’s reputation.
Kirkpol is out on bail but is hunted by angry gamblers. Lookmee makes a burnt breakfast for Touchma, which he eats to encourage her. Kamnan Ther tries to force Touchma to work at a pig farm owned by Duang Samorn, a widow who likes young men, because Kamnan has a crush on her. Touchma refuses and declares his love for Boonjira. Lookmee accepts Touchma as her new dad.
Kamnan brings Duang Samorn to the farm. Songsak meets her and falls in love. The kids prank Duang Samorn with a ghost act. Touchma proposes to Boonjira, who accepts. The farm gains fame as a rehabilitation center for racehorses. Kamnan accepts the marriage.
On the wedding day, Kamnan brings a large dowry. Det Duang Daraka walks normally again. Touchma becomes the permanent cowboy of Satan Suang Farm, living happily ever after.
