A tale of love, jealousy, and ambition unfolds within the Somsuriyan family, an old and wealthy clan in Phuket. Behind the walls of their grand Sino Portuguese mansion lie long buried secrets, while strict traditions and class divisions dictate the lives of every daughter in law, who is expected to be flawless, obedient, and self sacrificing. Oranee, the daughter of a humble rubber tapper, falls in love with Sant, the family's direct heir. Their relationship is met with fierce opposition from Tongta, Sant's controlling mother, and the other daughters in law, who never accept Oranee as one of their own. Meanwhile, someone within the mansion watches her with an unreadable gaze. As she is pulled into a ruthless struggle for power, status, and inheritance, Oranee must decide whether she will become another pawn in the family's game or the woman who claims the throne everyone desires.
