Crash Landing on You tells the story of two star-crossed lovers, Yoon Se-ri (Son Ye-jin), a South Korean Chaebol heiress, and Ri Jeong-hyeok (Hyun Bin), a member of the North Korean elite and a Captain in the North Korean Special Police Force. One day while Yoon Se-ri goes for a short paragliding ride in Seoul, South Korea, a sudden tornado knocks her out and blows her off course. She awakens to find her paraglider had crashed into a tree in a forest in the DMZ in North Korea (an area forbidden for South Koreans). She then meets Ri Jeong-hyeok and falls into his arms when descending from the tree. Ri Jeong-hyeok eventually gives Yoon Se-ri shelter, and develops plans to secretly help her return to South Korea. Over time, they fall in love, despite the divide and dispute between their respective countries.
