Tae Gong-shil, the "ghost whisperer," is a misunderstood misfit who has been unable to keep a boyfriend or a job ever since a near-death experience caused her to see desperate spirits. She feels obligated to assist them in resolving their earthly troubles so they can proceed to the afterlife, while he feels compelled to believe she is insane. As time passes, their lives intertwine in a tangled web of shenanigans, misunderstandings, and... yes, love.
