After the sudden death of Tanapop, head of the Julapakborirak family and chairman of JPB Group, his daughter Metinee survives the plane crash that claimed his life. Suspicious of foul play, she believes her stepmother, Getsara — now promoted to chairman — is behind it.
Determined to uncover the truth, Metinee enlists her brothers, Wayu and Kampanart, to investigate. But complications arise when Wayu, torn between loyalty and emotion, starts falling for Getsara and refuses to believe she's guilty.
Meanwhile, Getsara's ex, Passon, returns and begins manipulating the family from within. He uses his niece, Nuengjai, who is planted as Wayu's secretary, to spy on the family. As Passon uncovers Wayu and Getsara's growing bond, he works to destroy their relationship — fueling a dangerous game of power, betrayal, and revenge.
