Im's first international prize-winner (best actress for Kang at Venice) is a more-in-sorrow-than-in-anger attack on the principles of male lineage and ancestor worship in the traditional Korean family. It's set in the late Yi Dynasty (late 19th century) to stress how deep rooted these things are, but its resonances are squarely contemporary. The well-born Shin and his wife are happy but lack an heir; behind his back, the family conspires with his wife to bring in a surrogate to bear him a son. Their choice is Ok-Nyo (Kang), a free-spirited girl who endures various physiological and sexual indignities (intended to ensure that she produces a boy) because she comes to like Shin and enjoy the relatively pampered life - forgetting she is there only as a servant. The emphasis on female suffering has come in for some critical stick, but Im's analysis of Confucian blockages in the Korean psyche seems all too cogent. And his mastery of image, tone and rhythm is unassailable.
