The drama documents the rise and fall of three entrepreneurs, who founded Lik Tien Century Construction (力天世紀) together to achieve the ultimate goal of developing a pollution-free city in Hong Kong. Vendetta and love serves as strong subplots throughout the series, with the vendetta between two families being the most prominent.
The stories covered a span of 20 years, from 1990 to 2010, and featured many technologies that came to age during this time, including the nascent internet, and a bulkier tamaguchi virtual pet device (shown as a device similar to Game Boy in the series), which was developed by one of the entrepreneurs before his entry into construction.
