Ting is a young girl with a sight that most people do not have: she can see the spirits that occupy the same space as the living. This leads to an unexpected friendship with a young ghost named Xiu, who is searching for something that will allow him to find peace. Together, moving across the border between the real world and the spirit world, they face challenges that neither could handle alone. The nature of Ting's ability — whether it is a gift or a curse — is something the journey will force her to examine directly.
