Famous celebrity, Gu Xin, unknowingly caused the death of three individuals who became wandering souls. These souls refuse to leave Gu Xin alone until she helps to reduce their "weight" by fulfilling their last wishes before they can head for reincarnation.

Through the journey, the cold and aloof Gu Xin learns the true meaning of love and letting go.
