Two years into her marriage, Mei lives with her husband and her father-in-law. Having lost her mother to divorce at a young age and grown up without a father, Mei always saw her father-in-law as a true father figure. The three of them living together seemed like it would bring nothing but happy days—until a bottle of alcohol from the father-in-law's friend triggered an unexpected tragedy. Normally gentle and kind, her father-in-law undergoes a drastic change when drunk, revealing himself to be a sexually aggressive, extremely perverted old man with terrible drinking habits. What follows is a twisted relationship between Mei and her father-in-law—one she can never tell her husband about—and her life takes a dramatic, irreversible turn.
