In the midst of war, four young men fall in love.
In 1765, as the invading Angwa (Burmese) army marched towards the capitol of Ayutthaya Kingdom (Siam), they encountered little resistance from the Ayutthaya army, who retreated to defend from behind the capitol's walls.
Three childhood friends, in the Ayutthaya army, are constantly at odds. Thap wants to fight bravely, as Sang and Khap follow orders and retreat. Unhappy with the army, Thap defects and joins a group of patriotic rebels who eventually all gather at the village of Bang Rajan to defend against the Angwa.
Thap is patient, brave and righteous. Sang is hotheaded, stubborn, and overbearing. He is also ambitious and knows how to talk his way to a promotion. Khap is gentle, follows Sang's lead, but is also smart and wise to Sang's bravado. Sang is competitive and wants to win over Thap, but their personalities are not the only thing driving the rift. Sang loves Juang, Thap's sister, while Khap is madly in love with Feung, Thap's fiancee.
Thap does not want his, or Feung's family, to retreat to the capitol, although he has to be in hiding as a deserter. Sang takes this opportunity to be the protector of Juang and Feung. He convinces Khap that they must kidnap the girls and take them to the capitol for safety, while Thap is in pursuit to retrieve them. Also for the girls' protection, Sang and Khap declare that Juang and Feung are their wives. Along the way, they meet the mysterious Jai, who has fallen for the brave and patriotic Sapai.
The village of Bang Rajan, according to Thai tradition, is where a group of brave villagers, gathered from various regions, put up a brave fight and fought eight battles against the well organised invaders and became legendary heroes. The battle for Bang Rajan is a symbol of determination and heroism against overwhelming odds.
Bor (Pong Nawat) and Kaew (Aom Piyada) are lovers who are about to get marry. Then, tragedy strikes. Bor’s older sister, Putt (Pin Kejmanee), murders Kaew’s older sister, King, because she believes her sister and her husband (James Ruengsak) are having an affair. Naturally, after the killing, Kaew forces herself to break up with Por.
There is a time jump of six years. During those six years, Kaew stayed in Rayong withher mother and brother, Kong (“Fluke” Thammon aka Fluke: the Star 5), in their father's beach house. Bor has become a successful businessman and moves to Hong Kong to manage a company branch there. However, they both are reunited again after Kaew moves her family back to the city (to treat her mother's medical condition) and Bor returns back to the company in Thailand to be with his beloved niece, nu Nim. Under various events, Kaew ends up working as Bor's personal assistant and encounters Bor's girlfriend, Awn (Mod Jirachaisakdecha). Pueng (Peemai Wattanaselarat) is Kaew's best friend and also works in Bor's company. She likes a co-worker named Nuthi (Premanat Suwannannon), but Nuthi is instantly interested in Kaew upon seeing her for the first time. Bor is enraged with his past girlfriend/fiancee's relationship with a younger man, but at the same time, he cannot endure the hurt and pain that Awn, Putt and Pipat put Kaew through and vows to protect her, the only woman he's ever loved.
