Abracadabra

In 1980, a crack team of Taoists (garbed like ninjas!) successfully vanquish a mob of ghosts -- except for 80's demon babe Pinkish Red, who manages to escape. Six years later, Cici Shin (Charine Chan Kar-ling) and her cousin, Lily Li, 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 within it and, when Cici cleans the mirror's surface, the ghost is able to enter back into the temporal world.
