The Cursed Lesson

synopsis

Online fashion model Hyo-jung faces the imminent threat of being unemployed because of the younger and more fashionable generation coming after her. While relying on surgical procedures and treatments, Hyo-jung hears about a mysterious yoga class that helps improve people's bodies from her old high school classmate, Ga-young. Hyo-jung eventually attends the yoga class with three classmates: Mi-yeon, a boxer who failed to keep her body fit, Ji-won, who has an unstable mental condition, and Ye-na, a movie star who is morbidly obsessed with her appearance. Meanwhile, police start to investigate the enigma behind this yoga class after finding out that a murder in the neighbourhood was committed by a woman named Bo-ram, a former student.
