雷達驃任職「衛星電視」（本片虛構的電視台，與後起的衛星電視有限公司無關）新聞報導員，與驃嫂及三名女兒帶弟、來弟、招弟居於沙田新翠邨。驃嫂為典型家庭主婦，閒時喜與鄰居打麻將，又常常買六合彩，希望一朝發達、可以向親戚街坊炫耀。
某一天，驃嫂真的中了六合彩頭獎1,900萬港元。正當一家五口萬分興奮、在計劃怎樣用這筆橫財時，誰知銀行倒閉，而且亦有人趁機綁架……
雷達驃一家雖然失去了橫財，但是生活總算安穩。雷達驃後來轉職為報館編輯，在一次偶然的機會之下被派到加拿大溫哥華工作，他滿以為可以重新起步之際，原來只是一場誤會。最後，雷達驃更被上司開除。雷達驃只好黯然與家人回香港，並且在沙田沙角邨居住。
回到香港，正當各人收拾心情、過著默默耕耘日子的時候，驃嫂赫然發現自己所買的加拿大649彩票竟然中了頭獎，但雷達驃與驃嫂須設法返回加拿大領獎才行……
雷達驃一家在加拿大中了巨獎，樂也融融。回到香港後，驃嫂初為大富，難免意氣風發。有一次，當她帶朋友到大豐銀行「參觀」鈔票時遇劫，錢財盡失，雷達驃一家無奈只好再次搬回公屋。
某一天，雷達驃為生計前往電視台試鏡，巧遇兒時好友鹹酸菜（葉麗儀飾），驃嫂誤以為二人有染，因而引起一場小風波。後來，雷達驃接到銀行通知，承認保安失當，願奉還巨款……
Like many Hong Kong people, the Ling family are hoping to immigrate to Canada - but then they all die in a gas poisoning accident. Something wimpy like dying isn't going to stop them from their Canadian dreams, but it turns out migrating in the next life takes money, too. In order to raise funds to head west, the Lings return to the mortal world and get to work making money through various jobs, raising plenty of hilarious havoc and misunderstandings along the way.
A large family decide that they must find a bigger place because their current flat is too cramped and triads are threatening to burn them down to pass a message on to somebody down the corridor. So after being mucked around by an agent selling a house in the country, they move into a dilapidated house. They then discover that it is going to be torn down and a huge shopping centre erected.
