On a rainy night ten years ago, a taxi drove into the rain on Baoding North Second Ring Road carrying three strange passengers. The driver, Han Zhiguo, insisted that he had only picked up a woman in a red dress; but the strange text messages and fragmented memories on his phone kept revealing a horrifying fact: there were three people sitting in the car that night - but he was the only one alive to this day.
In the next ten years, Han Zhiguo had the same nightmare repeatedly: rainy nights, rearview mirrors, black shadows. Until one midnight, he picked up a strange passenger again and was dragged into a psychological maze from which he could not wake up. Text messages, files, phantoms, thunder on rainy nights... Reality and hallucinations intertwined, and he gradually discovered that he might be the only insider of the "disappearance case", and even the hidden perpetrator.
