Yin Yang Road 17: There's a Ghost in the Cell (Cantonese)

Bi Ji picked up a pack of drugs in a bar, and when the police appeared at the right time, Ji was accused of drug trafficking and later sentenced to prison. Long Di returned to Hong Kong from abroad and learned that Bi Ji had gotten into trouble. She hurried to visit Bi Ji in prison and noticed something was off about his complexion, deducing that he was being haunted by a female ghost.
