Bio Zombie - Sun faa sau si (1998)
Hong Kong's answer to George Romero's Dawn Of The Dead. A soft drink tainted with bio-chemicals has the power to turn people into flesh-eating zombies. A man drinks from the bottle, and wanders into the night. As two young VCD sellers (Woody Invincible and Crazy Bee) from a local mall are returning to the mall with their bosses' car, they hit the man. Unsure of what to do, they bring the man back to the mall with them. The mall closes, and soon there are zombies everywhere! A small group of mall employees must bond together to try and fight their way out.
