It's the end of the century at a corner of the city in a building riddled with crime - Everyone in the building has turned into zombies. After Jenny's boyfriend is killed in a zombie attack, she faces the challenge of surviving in the face of adversity. In order to stay alive, she struggles with Andy to flee danger.

One month earlier, Shang Zhen (Lynn Hung) arrives in Seoul, South Korea, where she coincidentally meets Jian Yu (William Li), who had his marriage proposal rejected. Shang Zhen, who is still heartbroken, had a sudden idea: to use Jian Yu to sabotage her ex-boyfriend's wedding. Thus, Jian Yu follows Shang Zhen back to China, where she reveals her "wild" side. Shang Zhen's cousin, Yong Zhen (Feng Yuanzhen), is also much of a headache for men. Working as a Taekwondo coach, Yong Zhen has a student named Zhi Kai (He Jiong) who lacks masculinity. Zhi Kai admires Yong Zhen greatly but often suffers under her fists and feet. Jian Yu accompanies Shang Zhen in preparing for the wedding sabotage, but during a rehearsal, they offended a stranger. Meanwhile, the wedding date is fast approaching. The film is an unofficial sequel of the 2001 South Korean film "My Sassy Girl".
