Introduction
Lin Xue, a former female entrepreneur, jumped to her death in full public view. There was no suicide note and no signs of struggle at the scene. Surveillance footage showed her walking to the edge of the rooftop with a smile on her face. Former detective Zhou Muye was commissioned by the deceased's best friend Su Jin to investigate, but found that all the clues pointed to the same 'suicide' that his wife had committed three years ago. At the same time, lawyer Zhao Ancheng intervened in the case and accidentally uncovered the connection between his father and the real estate group. When the truth touches the core of the power network, Zhou Muye and Zhao Ancheng, one in the open and the other in the dark, work together to tear apart the city's dirtiest fig leaf - but they don't know that the person who jumped from the building is still alive.
