Fong (Eric Wan) is a Chinese resistance fighter from the time of the Second Sino-Japanese War. In 1938, he was fighting with a Japanese lieutenant when they were interrupted by the appearance of the Vampire King. The two men and a boy named Fok Sung living the nearby village were bitten and they become vampires. These vampires are creatures that exist beyond the Three Dimensions (Heaven, Earth and Humanity) and Six realms, where all other beings, including animals, humans, deities and spirits, exist.
In present-day 1998, Fong lives in Hong Kong under a new name. His physical appearance has not changed since 60 years ago. Fong works as a policeman and Fok Sung lives together with him as his "son", who currently attends primary school. Ma Siu-Ling (Joey Meng) is a ghostbuster from the Ma family, which has co-operated with the Taoist Mao family for generations in ridding the world of evil supernatural beings. Ma falls in love with Fong and they begin an epic love story which withstands the test of time.
