In the "City of Paradise" in 2150, the sports car of Zheng Ke, an upper-class boy, accidentally rear-ended a garbage truck belonging to Zhu Yajing, a low-class girl. During the conflict, Zheng Ke discovered prohibited cyber garbage in the car and suffered a fatal blow from the company's guards. At the critical moment, Zhu Yajing burst out with amazing power of the prosthetic body. After being on the run, Zheng Ke learned the cruel truth: the girl's parents had turned into the garbage truck she relied on for survival and the prosthetic body fused with her spine. A rear-end collision broke the barrier between the two worlds.
