Sang-min comes to Finland to send her autistic son to a special camp, but she feels extremely alienated in snow covered-white Helsinki. Ki-hong is an architect working in Finland on dispatched duty. His family is not so perfect either with a daughter having child depression and mentally unease wife. The two meet for the first time at the gathering point of this special camp. They get to have a short trip to the camp together in silence but start to feel comfortable and connected to each other. On their way back to Helsinki, with the road blocked from heavy snow, Sang-min and Ki-hong are isolated in a cabin by the forest and lake. Carried away by irresistible passion, they spend a night together.
