Based on a well-known Thai erotic novel, the film narrates the tale of Jan, a young boy raised in a household dominated by his cruel and immoral father, Luang Wisnan. Set in the 1930s, the narrative explores Jan’s tumultuous upbringing, marked by the death of his mother during childbirth and his father’s deep-seated animosity towards him. Jan is raised by his stepmother, Aunt Wad, and grapples with feelings of guilt and desire as he navigates relationships with various women in his life. Among them is a girl named Hyacinth, whom he deeply admires, and later, Madame Boonleung, his father’s mistress, who plays a pivotal role in Jan’s sexual awakening.
