Xie Xiaodong escaped the disaster of life and death by following the three walnuts left by his crazy grandfather. The first walnut helped him avoid human traffickers and met undercover policeman Tang Min; the second walnut revealed the true identity of his ex-fiancée, so he decisively escaped from marriage; the third walnut was exchanged by his enemy, but he still followed the prompts and smashed the mirror to discover the murder. In the end, he saw through the revenge plot of Haonan, a family member of the human trafficker, and Liu Ruyan, the disguised lover. With the help of Tang Min, he brought the criminals to justice. After three disasters, he finally found peace and ushered in a new life with Tang Min.
