Chaloey Sak(2010)

Chaloey Sak is a Thai drama following Lieutenant Yothin Warat, a decorated WWII hero of the Free Thai movement with a promising future and an engagement to a minister's daughter. When Yothin's father faces financial ruin in his shipping business, a ruthless businessman named Atisak seizes the chance to exploit the family's desperation. He offers to save the company in exchange for holding Yothin prisoner for a year at his estate—payback for an old family slight. Atisak's sister Alisa, who supervises the captive lieutenant, harbors her own romantic entanglement with a dissolute prince from a neighboring kingdom. Trapped between duty, family honor, and unexpected connections, Yothin must navigate a web of revenge, ambition, and desire that threatens everything he holds dear.
