The Biu Family collects their lottery winnings in Canada and returns to Hong Kong to start a new life together, minus the second daughter due to a family quarrel of her involvement with her boyfriend. After Mrs. Biu shows off her money to her old friends at her bank, she loses it all in a robbery. Now, void of their new found wealth, the Biu Family must start over from scratch again.

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.

After losing their lottery winnings during the bank's closure, the Biu family's luck changes again as Bill's job promotion and daughters' education and work careers sent them and the entire family to lead their new lives in Canada, where new misadventures await.

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.

Bill, a TV news reporter, tries to make ends meet to support himself, his wife and three daughters in urban Hong Kong. In the mist of the misadventures of Bill and his family, their luck and lives ultimately change when Bill's wife suddenly wins the lottery.
