Wang Youwei (played by He Haochen), a typical loser, is an alternative service member in the Legislative Yuan. However, in the conflict between legislator Xiong Yingying (played by Lai Ya-yen) and the villain legislator, Xiong Yingying accidentally resigned. She then strongly demanded Wang Youwei to re-elect her as a legislator. Wang Youwei, who had never even been a class monitor, was elected as a legislator in this way! One day after he took office, a zombie virus broke out in the Legislative Yuan from a chemical plant, and senior legislators bit each other and turned into zombies. Wang Youwei found that he was immune to the virus. He and the survivor Xiong Yingying decided to blow up the zombies and escape from the Legislative Yuan, because they all wanted to get out alive, and no one could be left behind!
