Shin Sang-gyu has a problem: he is the last male heir in his branch of the Shin clan, and despite the close relationship with a beautiful and still young wife, they have no children, no son to carry on the family line. Uncle and grandmother confer and decide to seek out a surrogate from a village of women known for providing such ‘borrowed wombs’. Ong-nyeo, only seventeen, is chosen for the role. When passion carries her and Sang-gyu well outside the limits prescribed by Confucian family duties, the result will prove lethal.
