On a July night beneath the "supermoon," workaholic Qiao Xiaoman mysteriously disappears from the Mingyang Seaside Resort Hotel. It is a secretive mystery that took place in Mingang City that summer. After witness accounts come to light and the police investigate, Qiao Xiaoman is believed to have jumped to her death from Yushan Cape, near the hotel. Was she troubled by love, worn down by work, or worried about her family? Why would a perfectly ordinary white-collar woman take her own life?
As Officer Li Xing investigates the cause of Qiao Xiaoman's death, he gradually enters the dead woman's social circle. Beneath the calm surface of her disappearance lurk hidden, turbulent currents: a callous boss, a subordinate eager to climb the ladder, relatives living far from home, and old friends long out of touch...
As Li Xing slowly pieces together Qiao Xiaoman's life, he discovers that stereotypes and gender bias alike trapped her in an inescapable "female predicament." Yet this "female predicament" did not disappear when Qiao Xiaoman went missing. It continues to tighten its grip around the women in her life... even Li Xing's ex-wife and colleagues are not spared. Will they eventually take their own lives for the same reasons?
