Qiao Shi, a gloomy and taciturn restorer of old objects, has the special ability to read the memories of old objects. He lives alone in an old alley all year round and has nothing to do with the world. In a well-planned car accident, he accidentally switched bodies with Lin Mo, a wealthy young man. After waking up, Qiao Shi was forced to assume the identity of "Lin Mo", dealing with wealthy power struggles, fatal pursuits and interlocking conspiracies, becoming the perfect stand-in for Lin Mo's revenge plan; and Lin Mo, who was hiding in Qiao Shi's body, was using the cover of an old alley repair shop to advance a revenge plan that spanned more than ten years. As Qiao Shi's special abilities continue to be triggered, the truth about the fire and murder fifteen years ago, the mysterious Apocalypse organization, the shady story of human experiments, and the mystery of the brothers' life experiences gradually emerge. Two people bound by fate, from mutual use, opposition and suspicion, to being forced to join forces. In a life intertwined with falsehood and danger, they must not only tear apart the mystery of the substitute, but also fight against the huge dark forces, and finally take back their own lives and seek justice for the people who have passed away.
