Martial arts instructor Mad Bill (Samuel Hui) was recently dismissed from his job and applies for a position at the magazine company.

However, Hui runs into another "ghost", who, unbeknownst to the trio, is part of a gang seeking to drive the filmmakers away from their area of operations.

The trio then decides to spy on Sandy Cheung (Catherine Hung), who has a reputation for purity and innocence in the entertainment industry, and is set to marry the son of a jewellery magnate.

They follow her to a beauty salon, planning to take photos of her having a breast enlargement, hoping to cause a scandal, but she turns out to be there for routine skin care.

The night before publishing the news, Bill and Fly's consciences catch up with them; they take the negatives of the photos and return them to Sandy at her engagement party.
