Bangrab Choa Phnom-40End,វិរៈបុរសបង្រ្កាបចោរភ្នំុំ​, Nai Hoi Tamin (Thai adaptation) Native Title: นายฮ้อยทมิฬAlso Known As: The Lethal Rancher , Nai Hoy Tamin Nai Hoi Tamin is about the difficult life of the people of the East of Thailand – in a time when drought and poverty forced them to bring their buffalos for sale around the center of Thailand. There was a strong leader, “Nai Hoi Tamin”, who led the big caravans for the long and sometimes dangerous trip. Along the way, they had to deal with many kind of hardships, such as robbers and thieves, illness, and the difficulty of traveling. Kumkaew was the younger sister of Nai Hoi's wife, Kumpang. Kumkaew was very kind, but had a strong and confident personality. She loved her sister very much. However, she did not accept Nai Hoi's job, because he left Kumpang with her during his long journeys with the buffalo caravans. At the beginning of the story, Kumpang died of poor health and the heartbreak of missing her husband too much. After Kumpang died, Kumkaew kept the promise that she gave to her sister – that she would take good care of Nai Hoi and would not let any girls come close with him. She hid herself to secretly join the buffalo caravans. It was too late for Nai Hoi to send Kumkaew back after he found out that she was there. After some time, Kumkaew surprised herself as she fell in love with her sister's husband, and he also grew to fall in love with her as well.
