Mr. Kim (Jung Jae Young) attempts to commit suicide by jumping into the Han River, but he fails to drown. Waking up on a nature preserve island in the river, he begins a new back-to-basics life on the deserted island. His exploits attract the curiosity of lonely apartment recluse Miss Kim (Jeong Ryeo Won), who watches his comings and goings through a pair of binoculars from her high-rise window. Miss Kim hasn't left her home in three years, but seeing Mr. Kim's strange adventures inspires her to take the first step into the outside world.

Jung Jae Young (The Divine Weapon) and singer-actress Jeong Ryeo Won (The Two Faces of My Girlfriend) star as two lonely social castaways who cross paths in the quirkiest of ways in the charming oddball dramaCastaway On The Moon (a.k.a. Kim's Island). Award-winning Like a Virgin co-director Lee Hae Joon injects his first solo feature with the same offbeat, affecting humor and sensitive insight that made his first film a critical hit.
