Synopsis

Zhong Bufan (Peng Yuchang), a broke tenant struggling to make ends meet in the city, never imagined his life would take such a bizarre turn — when his elderly landlord, Ren Jiqing (Jackie Chan), mistakes him for his long-lost son!

With no savings and nowhere else to go, Bufan ends up stuck under the same roof with a hilarious bunch of oddballs — Su Xiaoyue (Zhang Jianing), a drifting tenant with her own dreams; Jia Ye (Pan Binlong), a middle-aged “slash” housing agent who thinks he knows everything; and Jin Zhengu (Li Ping), the nosy but warm-hearted neighbor who treats everyone like family.

They’re not related by blood, but fate — and cheap rent — bring them together. Between Ren Jiqing’s unpredictable memory lapses, endless mix-ups, and bursts of fatherly affection, Bufan’s life becomes a rollercoaster of laughter, chaos, and touching surprises… until he discovers the old man’s secret that changes everything.
