Yu Miaomiao is a twenty-two-year-old woman living a solitary and financially strained life in a rented apartment with her pet dog, Maodou. She has no close family and works a low-paying job that she resents. One evening, she returns home to find a man in a black suit sitting in her living room. He reveals himself as a Soul Ferryman from the Underworld and informs her that her life span has expired and she is scheduled to die that night by electrocution while showering. The Soul Ferryman, who is new to his position and worried about losing his monthly bonus if he fails to collect a soul, is desperate. Yu Miaomiao pleads for her life, not for herself, but because she fears what will happen to her dog if she dies without a new owner. The Soul Ferryman explains that the only way for her to survive is to borrow life span from recently deceased individuals who have unfinished wishes. If she helps them fulfill these desires, they may grant her days of their own life span in the next cycle.

Yu Miaomiao agrees to help, and the Soul Ferryman finds her first client: an elderly grandmother who refuses to reincarnate because she was buried next to her abusive husband against her dying wish. Yu Miaomiao travels to a cemetery at night and digs up the grandmother's urn. The woman’s final request is to have her ashes scattered into the sea so she can see the world she was confined from for decades. Yu Miaomiao complies, and in return, she receives three days of life span. She also inherits the grandmother's gold jewelry, which she sells to fund her remaining days. With her immediate death postponed, Yu Miaomiao quits her job and begins to enjoy her newfound freedom, treating herself to expensive meals and simple pleasures she had previously denied herself. However, her primary concern remains finding a loving home for Maodou before her time runs out.

The Soul Ferryman then presents a second case involving a young woman who died after discovering her husband’s infidelity. The woman refuses to move on until the cheating husband and his mistress face public retribution. Yu Miaomiao, using her human identity, helps steal the mistress’s phone and exposes their affair to the husband’s entire company during a live meeting. The scandal goes viral, causing the couple to lose their jobs and turn on each other. The deceased woman, seeing justice served, finally agrees to reincarnate and grants Yu Miaomiao five additional days of life span, along with a significant sum of money. Yu Miaomiao now has eight days left, but she is determined to extend her time further to secure a future for her dog.

A third case arises involving a university student named Zhang Xiaolan, who died of cancer while her grandmother, suffering from Alzheimer’s, waited for her return. Yu Miaomiao travels to a remote mountain village to impersonate Xiaolan and visit her grandmother. During her stay, she experiences the warmth of family love that she has never known. On her way back to the airport, she is kidnapped by a man who intends to sell her. The situation is resolved when the man’s truck goes over a cliff, killing him. The Soul Ferryman appears, revealing he had sent a colleague to protect Yu Miaomiao. He takes the kidnapper’s soul and grants Yu Miaomiao the remaining three days of the man’s life span. She returns home with more time, money, and a piece of valuable ginseng. The story concludes with Yu Miaomiao continuing to help spirits find peace, extending her life day by day while searching for a permanent home for Maodou, navigating the boundary between the living and the dead with the assistance of the Soul Ferryman.
