Not only people have to come up with brainy ideas, but zombies also have to engage in "eating brains" literally. Chav Yu Yeung-kwong (Matthew Ho) loses his mind and rushes to the morgue as he shockingly notices something unusual about his body. He eats a bloody human brain in front of his buddies, forensic intern Koo Tak-ming (Arnold Kwok) and doashi Wah Lun (Milkson Fong). Since then, Yeung-kwong possesses someone else's memory and skills when he eats their brain. One day, Yeung-kwong is so hungry that he wants to eat the brain of Mok Siu-chun (Kaman Kong), who is the daughter of some mahjong school boss. The duo get acquainted after a fight. After becoming a brain-eating zombie, Yeung-kwong uses other people's brains to experience all kinds of wonderful life moments. These experiences eventually result in him being somewhat enlightened, and so he decides to keep running his family hotpot restaurant business. Meanwhile, Yeung-kwong's granduncle Yu Gor (Ram Chiang) eerily shows up and disappears around him. He even reveals the Yus' secrets. And a zombie disaster is also looming.
