During the Republic of China, a series of bizarre and murderous crimes that violated common sense occurred in the Shanghai Concession. Zeng Jiahe accidentally awakened his personal storage space and became a partner with Wen Xu, a detective who had returned from studying abroad. Relying on the special evidence stored in the space, the two teamed up to dismantle the serial conspiracy hidden under the surface of the strange stories. They protected innocent people in the tightening legal trap and gradually uncovered the truth of old cases that had been sealed for many years.
