Luead Jao Phraya (Chaopraya Bond)

Lan The, Ayutthaya is a remote area far from civilization where the law holds little meaning and the use of brute force is a common occurrence.
Srinuwan, the daughter of the local Kamnan (Sub-district Headman) Thong, is beautiful, talented, and as brave as any man. She is desired by many local men, including Saming, an ordinary villager.
During Srinuwan’s 20th birthday celebration, Banlue, the son of the influential Tycoon Chin, causes a disturbance and shoots Saming’s parents dead. Saming vows revenge for his parents, but Tycoon Chin, having connections with local officials, frames Saming as the culprit. Saming is forced to flee into the forest and hide with the bandit gang of Tiger Hien at Chong Lom Cliff. Meanwhile, Tycoon Chin is aided by Tiger Mahesak, a notorious and ruthless bandit.
Lersan, a young police cadet and the son of the provincial governor who owns much land in Lan The, visits the area during his school break to gain experience. He meets Srinuwan while she is performing Lam Tad (a traditional folk song) and falls in love with her. Srinuwan reciprocates his feelings, which causes great pain to Saming. However, Saming understands their love and asks to befriend Lersan.
Later, Srinuwan and Lersan secretly consummate their relationship, which Kamnan Thong eventually discovers. Lersan declares he will take responsibility by marrying Srinuwan, asking for three months to finish his studies first. On his journey back to Bangkok, Lersan gets into an accident that causes amnesia, erasing all his memories of Lan The. upon his return, his mother arranges for him to marry Soiphet, the daughter of her close friend.
When Srinuwan and Kamnan Thong travel to Bangkok to reclaim his promise, Lersan, with his lost memory, does not recognize them. Both are deeply disappointed, causing immense resentment in Saming, their close friend.
20 years later, Lersan has become a Deputy Commander in the Crime Suppression Division. He has a son and a daughter with Soiphet. Meanwhile, Srinuwan has raised a daughter—Lersan's child—who is as skilled and formidable as her mother.
Lersan, along with Rapee, a young police officer under his command, finds it necessary to return to Lan The once again. And there, the memories and stories of 20 years ago slowly begin to return.
