An assassin known as Wind Yip (Sharla Cheung) is thought to be a robot after she is seen ripping the guts out of the president of a large corporation and dodging a hail of bullets from police. Later, she shows up at the corporation to steal the Diamond of Emperor Chen which is the key to a vast treasure. But another group of thieves, led by Ko Kit (Anita Yuen), are also trying to steal the diamond for their boss who has labeled the operation the Crystal Fortune Run. After guards are alerted, Ko takes the jewel and leaves Wind to fend off the guards.

In 1980, a crack team of Taoists (garbed like ninjas!) successfully vanquish a mob of ghosts -- except for female demon Pinkish Red, who manages to escape. Six years later, Cici Shin (Charine Chan Kar-ling) and her cousin, Lily Li (Ann Bridgewater), open a boutique and need a mirror for their fitting room. The mall security guard finds one for them in the basement but, naturally, Pinkish Red resides inside it and, when Cici cleans the mirror’s surface, the ghost is able to enter back into the real world.
