Outside the ICU, 21-year-old Lin Xiaoyue bumped into the "soul guide" hovering in front of her grandmother's hospital bed, and even met a white-clothed ferryman who called himself Xie Bian. He held the life and death of her grandmother in his hands, but he offered a deal: as an intern ferryman, he could extradite 44 obsessive souls in exchange for her grandmother's longevity.
From then on, she transformed into a "two-faced person". During the day, she was an ordinary student guarding the hospital. At night, she used the soul boat on her wrist to travel between yin and yang, helping the boy squatting at the intersection to settle his golden retriever dog, and fulfilling the wish of the stranded old man. But the obsession of the dead soul follows her like a shadow, and the rules of yin and yang are strict and cold. She must not only protect her grandma's life in the human world, but also protect herself from being swallowed up by her obsession in the underworld. This journey of exchanging lives for lives has just begun.
