Jiangcheng City is always shrouded in thick fog in late autumn, and the "Wangchuan Bridge" built across the river is looming in the fog, like a dormant giant beast. This bridge was built thirty years ago. It carries the prosperity of Jiangcheng and also hides countless secrets. Ten years ago, the famous architectural designer Shen Jingyan fell and died on the bridge. The police concluded that it was an accident. Now, his daughter Shen Yanqiu returned to China after studying and just took over the architecture office left by her father.
