A 70-year-old woman who dies from falling off a slow treadmill and finds herself as a soul hovering over her body in the hospital ER. She is a martial arts gym worker, fashionable enough to have notarized and updated her will annually. She has a good friend Sister Wang, a student Liu Xu, and deceased sisters Bi Qiuguo and Bi Xiahe. After death, her soul is sucked into a white light and she awakens on a shabby bus in what appears to be the past, specifically 1968, based on her joking wish. She initially believes she is in a variety show prank by Liu Xu, but soon realizes the setting is real when she encounters girls who look exactly like her long-dead sisters. She is bound near her body but can float, and she is confused about whether she is fully dead or hallucinating. Her life had been hard but decent in the latter half, and she had no children or relatives left except for mourners like Liu Xu.
