Version 1

The police academy is haunted. Instructors, SIR Chen and SIR Tang, found nine male and female police officers who belong to the dragon zodiac to practice chasing ghosts in Kowloon. Among them, Li is a female inspector who catches chickens and is determined to play tricks on her and make fun of her. Later, the students learned that the purpose of the training was to catch ghosts, so they immediately resigned, but the camp was controlled by ghosts, and they were forced to stay and help Mr. Chen drive away ghosts. In an emergency, they were forced out.

Version 2

Sir Tang and Sir Chen are police academy instructors. They met with evil spirits overnight, and all the students fled. It turned out that Mr. Chen had done a lot of evil in his last life, killing a family of four, turning them into four zombies and trying to kill him. Master Chen turned to Master Lai Da for help and got the secret of the Kowloon Soul Chasing Array. So he recruited nine male and female police officers belonging to dragons and trained them according to the teacher's instructions to prepare for exorcism. In a farewell mission called "VSOP", Sir Tang and Sir Chen cheated nine policemen. This mission was led by Li, a female inspector who caught chickens. Li's arrogant attitude caused dissatisfaction among the players. Playing tricks on her in the name of birthday party, making too many jokes. Little zombies are fun-loving, secretly making strange things, and it is difficult to accept classes. As a result, three big zombies appeared to clean up, and everyone was running around holding their heads. Nine players resigned immediately, but the training camp was controlled by zombies. They have no choice but to concentrate on practicing the Kowloon Soul Chasing Array and prepare for the battle. On the 14th day of the seventh lunar month, four zombies were dispatched, and the Kowloon Soul Chasing Array was also defeated.
