Wilson Yip directs the horror comedy movie Bio Zombie, in which a biological weapon has the power to turn people into zombies. Woody Invincible (Jordan Chan) and Crazy Bee (Sam Lee) are two kids who work at a video store in a mall. While driving their boss' car, they crash into an agent carrying the deadly weapon in a tainted soft drink. Putting him in the trunk, they go back to the mall. However, the dead guy gets loose and the mall eventually gets filled with zombies, with Woody, Bee, and their friend Rolls (Angela Tong) trapped inside. ~ Andrea LeVasseur, Rovi
