Ghost Killer (1992) on Netflix

Plot summary

A drug courier who goes by Lousy Chao is blamed for a substitution in the goods he carries, and his employer has both him and his wife Ngor put to death. Because the dead man cannot act on his own, his ghost hunts for a living person with the same birthday, and settles on Ming. Ming has just proposed to Hung, and the spirit takes over his body. Puzzled by the change in the man she agreed to marry, Hung brings her worries to her uncle Shun, a taoist. In the same criminal circle, a boss named Nan treats any talk of ghosts as nonsense, as does Ming.
