In a well-planned car accident, 30-year-old entrepreneur Lin Shu suddenly passed away. When he regained consciousness, he became a wandering spirit that could not be sensed or touch real objects - he could see the forbearance of his parents who hid antihypertensive medicine to support their funeral, heard his girlfriend Su Wan pouring out his longing for old photos, and saw the young Chen Yang being threatened in order to find out the truth about the "accident". The pain of being separated between life and death and the obsession of "protecting his relatives and friends" became the only reason for him to be trapped in the world.
By chance, he helped convey the last wish of a little girl who died in a car accident, and unexpectedly received the light-gold power derived from "gratitude" - this was the "power of faith" that allowed him to blow the paper and make a slight sound. From then on, Lin Shu embarked on a special path of cultivation: helping an elderly person living alone find a will, clarifying misunderstandings for a suicidal young man, and reuniting a separated mother and son... Every time an obsession is resolved, there is more strength, from a "twilight period" to a "semi-entity", and then to a "complete entity" that can be embraced by relatives and friends.
As his power grows, the conspiracy behind the car accident gradually becomes clear: his distant cousin Zhou Ming planned everything due to business resentment, and his former partner Zhao Kun became an accomplice. Lin Shu teamed up with Chen Yang, got acquainted with Lao Qin, who could communicate with the souls of the dead, and Xiaoya, a nurse, to form the "Guiyuan Pavilion". While using the power of faith to purify evil spirits and help more souls return to their wishes, Lin Shu collected evidence and finally brought Zhou Ming to justice.
From a powerless wandering soul to an eternal guardian of faith, Lin Shu spent his life proving that death is never the end. The bond with relatives and friends and the persistence of goodwill are the eternal return across life and death. Here are the concerns of parents hidden in old clothes, Su Wan's waiting across the years, and Chen Yang's belief that he has never given up.
