Little Ye-eun is dying. The child has a weak heart on the edge of failure, and if she doesn’t get a transplant soon it will be too late. Her mother, Yeon-hee (Kim Yun-jin), is desperate and willing to go outside the usual channels to find her daughter a heart. An opportunity arises from a shady source, but when Yeon-hee is introduced to the still-living man whose heart she’s meant to have she decides that taking advantage of his situation is going too far. And then her daughter gets even sicker. Hwi-do (Park Hae-il) is a wannabe thug always looking for the angle that will net him a payday. He constantly harasses his estranged mother for money, but shortly after she cuts him off for good with a final payout she has a stroke and ends up in a coma on life support. Knowing the woman’s prognosis is poor, Yeon-hee offers money to Hwi-do if he’ll pull the plug so the heart can go to little Ye-eun. What should be a simple (if not morbid) transaction soon spirals out of control when Hwi-do decides he wants his mother to live and Yeon-hee decides she’s done waiting.
