Xie Langfeng's grandfather left behind three life-saving walnuts, each of which guided him to avoid death at critical moments. From escaping from the hands of human traffickers, to discovering photos of his fiancée's "husband-killing" before the wedding, to the corpse in the secret room behind the mirror, behind the three crises was a revenge conspiracy that lasted for several years. In the end, he fought back against the double betrayal of his current girlfriend and best friend, and was reborn under the protection of his ex-girlfriend, a police officer.
