In the late Ayutthaya period of the Ayutthaya Kingdom, inquisitive Dao Rueng was raised by her Grandma Nim to be intelligent and independent. She found a kindred spirit in Khun Krai, a brave and honourable soldier, whose brother marries her sister. Muen Thip is a corrupt soldier and womanizer who becomes Khun Krai's rival and forces Dao Rueng to help him seduce Lady Yuern, Khun Krai's younger sister. When this is exposed, Dao Rueng confesses her part in the plot to Khun Krai. He forgives her and they become closer.

Khun Krai, his father, and Dao Rueng's brother are ordered to protect the kingdom from the Burmese Army, and in their absence, Muen Thip tried to marry Lady Yuern. Khun Krai is able to stop this, and Muen Thip collaborated with the enemy in an attempt to destroy Khun Krai. Both Khun Krai and his ally, Pan Singh are badly wounded in battle. Lady Yuern shelters and cares for Pan Singh, and they become engaged. However, because Khun Krai remains missing Lady Yuern is pressured to agree to marry Muen Thip. Khun Krai reappears and volunteers to fight again despite his wounds, and relocates the government due to Burma's advances.

After some time at war, Khun Krai and Dao Rueng are reunited and married, but he was ordered to the battlefront on their wedding night due to Muen Thip's meddling. As a soldier's wife, Khun Krai came to accept the losses of her life and became stronger. The Burmese Army breached the city walls, and Muen Thip's plans to switch sides were thwarted when he was mortally wounded by one of his servants. Khun Krai and a pregnant Dao Rueng attempt to escape the Burmese occupation when they meet Taksin the Great and joined his cause to liberate Ayutthaya territory.

Khun Krai continued to fight heroically and advanced quickly in the new military, but eventually died. Dao Rueng was strong for their children, who became her purpose in life, raising them to be dutiful and to serve the country, awaiting the day when it would be reunited.
