Chen Shi, a top killer codenamed "Razor", faked his death after getting tired of killing, and became a kindergarten chef incognito. He cuts vegetables with assassin-level knives, seasoning with poisonous precision, and makes delicacies that are "murderous" but make cute kids crazy.
Unexpectedly, Tiantian, the number one fan, is actually the daughter of the underworld boss Long Ge. Brother Long recognized Chen Shi's identity and drew his gun at him, but his daughter said "Don't bully my hero" and forced him to go to the real scene - asking Chen Shi to teach him how to cook.
An ex-colleague came to chase him but was bribed with food, the kindergarten turned out to be an intelligence station, and an old enemy organization came back... Chen Shi returned to his old career to protect the children, but found that he could no longer do without this group of noisy "ordinary people."
