Who Are You?

Son Il-Geon dies unexpectedly, leaving his daughter, Son Young-In, all alone and unprovided for. Worried about her and lamenting his misgivings as a father, he asks for more time so that he can help her out before leaving for the after-life. He is granted 49 days to deal with any unfinished business he might have left behind, so he gets sent back as a ghost and, for 3 hours every day, is allowed to take control over the body of Cha Seung-Hyo, a handsome and cold blooded businessman that had fallen into a coma the same day Son Il-Geon died.
