One evening in Na Khae village, Thong, a skilled subordinate of Pho Khun, the village headman, is forced to collect a debt for farmland from Old Phet—the father of Waew, Thong’s beloved. Unable to pay, Old Phet is compelled to sell his daughter out of fear of Pho Khun’s power.
Waew is brought into Pho Khun’s household to serve Duang, his daughter. However, Ming, Pho Khun’s son, constantly harasses her and tries to turn her against Thong by speaking ill of him. When Thong finds out, a fight breaks out, and he is defeated. Waew is confined for seven days, and Thong is forbidden from seeing her.
Later, Pho Khun orders Thong to steal cattle. Thong agrees, but only on the condition that Waew will be set free afterward. While Thong is away, Ming schemes to marry Waew. When Thong returns earlier than expected, he realizes he has been deceived. He rescues Waew and takes her to Wiang Khoi to treat her injuries.
Pho Khun places a bounty on Thong and his companions. Upon learning that Thong is hiding in Wiang Khoi, he leads a group to capture him, resulting in a violent confrontation. Thong is forced to surrender when Pho Khun threatens Waew’s father. In the end, Waew agrees to marry Ming to repay her father’s debt, leaving Thong heartbroken and resentful.
Two years later, Na Khae village falls into hardship, and no caravans dare pass through. A young Lao Song man named Saen arrives with a caravan—but in truth, he is Thong in disguise, returning to gather information. By now, Ming has become the new headman, as Pho Khun has grown old. Ming frequently abuses Waew and her child, believing the child to be Thong’s, while also seeking to take Soi, the beautiful younger sister of Son, as another wife. To achieve this, he forces Duang to marry Son.
Thong returns to Na Khae seeking revenge. However, he finds that karma has already punished Waew and Pho Khun, and he chooses to forgive them. Instead, he rushes to rescue Duang, whom Ming has abducted to Wiang Doi. In the end, Thong kills Ming and successfully saves her, bringing his long-held vengeance to a close.
