Sang-min comes to Finland to send her autistic son to a special camp. She feels so alienated in Helsinki. Ki-hong is an architect who works in Finland on dispatched duty. His family is not so perfect either with a daughter being treated for child depression and a mentally unstable wife. With each of their children attending the same special children’s camp, the two happen to journey on a short trip together. They start off in silence, but in strange comfort and a feeling of connection. On their way back to Helsinki, due to sudden heavy snow, they become isolated in a cabin by the forest and lake. And they find themselves carried away by irresistible passion. But the next day, they go separate ways back to their reality. Until one day, they come across each other again.
