The film stars Ananda Everingham and Laila Boonyasak as the doomed lovers Sangmong, and his uncle's wife, Yupadee, respectively.

He was a conservative man with traditional values, and his days consisted of reading books and working for his uncle.

While attending an international sport club in Bangkok, Ni Han meets a widow named Yupadee, and falling for her charms and modern ideas, marries her.

The two become close friends, which Ni Han encourages as he believes Yupadee will help Sangmong break out of his shell and become more sociable.

Sangmong meanwhile develops an infatuation with Yupadee, which grows stronger after she nurses him back to health from a fever.

Ni Han then announces he must leave on a business trip and decides to take Yupadee with him, but she fakes a pregnancy in order to stay behind and be alone with Sangmong.

The next day he reveals that he knows about them, and he gives Yupadee to Sangmong, chaining their wrists–so they can stay together until eternity–and banishes them to a small cabin in the woods.

Refusing to kill himself or Yupadee, Sangmong attempts to run away on a ferry that comes to the village every few months.

When Sangmong doesn't answer her, she refuses to allow him to break the chain and Ni Han's men find them, and they are taken back to the cabin.

The next day, the young man bravely goes to see Ni Han, who is surrounded by the three women and chains hanging on a column.
