At two o'clock in the morning, at the entrance of the funeral home, a female ghost in a red dress got into the car of the night shift driver Lu Ming. When she got off the bus, she left Zhang Ming's banknotes and a secret token. From then on, Lu Ming, who just wanted to live his life, was forced to take over the task of crossing ghosts. Under the old locust tree in the west of the city, a ghost has been waiting for him for ten years, just to see his grandson for the last time; locked in the cellar of No. 13 Yong'an Road, are the notes left by the missing grandfather, and an unfinished sentence: "The pen three years ago is not right." Before the winter solstice, he must find his grandfather back, take his life back, and investigate this bad debt from beginning to end. The coward is just pretending, but the bones are real.
