遲九線是正宗香港仔，過住疍家人的無憂生活，中了獎去日本旅行被偷光行李，回程時竟把導遊和小偷帶回香港；另一方面，日本財團口說友誼和發展地區經濟，但實質卻是推倒鮮花種大廈，於是全家總動員，對抗大財團！ 偏鋒特立的山本政志，拍出回歸前光怪陸離的香港，穿梭廟街、大澳、大阪和東京，九十年代的繁榮香港盡收眼底，見證一個時代的興盛；後段小市民對抗財閥，大叫過癮之餘，同時勉勵小市民，每個抗爭都有價值。

When a Hong Kong teenager from a poor family wins a trip to Japan, he unleashes a chain of events that will soon bring him from his secluded fishing village to Tokyo. On the way, he connects with a barely competent tour guide and a gender-fluid pickpocket. Upon returning home with this merry band of schemers, he and his family of counterfeiters discover that a multinational conglomerate led by a ruthless Japanese developer has found the village, and is determined to raze it to build the new center of world trade.
