Wei Song Yan comes back from the United States to open up a psychology clinic in Taiwan called Green Door. His meticulous ways and principles are getting in the way of the success of Green Door, despite his girlfriend, Hong Yu Mei, referring clients in his direction. The first clients he gets without the help of Yu Mei, however, turn out to be ghosts: the spirit of a young girl from the future that only appears in mirrors, the spirit of a gangster who is currently trapped in the body of Yu Xiu Qi and a spirit who can't move on from a past memory. Wei Song Yan attempts to help the spirits of the past, present, and future; while being haunted by the traumas of his own life.
