Late autumn of 1933, Shanghai. Xie Yungui, a banker who returned from studying abroad, met Lin Shuying, an independent woman working in a newspaper office, in the mist by the Huangpu River. He is a financial upstart, calm and self-possessed, carrying the secrets of his family and the times; she is a progressive reporter, sober and tenacious, with hidden past events hidden under her pen. Under the peaceful singing and dancing of the ten-mile foreign market, an undercurrent is surging - the Japanese invaders are approaching, forces from all sides are competing, and gold, intelligence, and conspiracies are intertwined in the dark night. When personal feelings collide with the interests of family and country, and when the fog peels away layer by layer, they find that they have met each other on the chessboard of fate. This is a love story about trust, sacrifice and choice in troubled times. In the smoke and clouds of Shanghai, some people are lost and others stick to it, and love and faith will eventually be tempered with the most dazzling light in the flames of war.
