Kuang Tianyou (played by Yin Tianzhao) and his "son" Kuang Fusheng (played by Zhang Guoquan) live in the modern downtown of Hong Kong like ordinary people. Few people know that their true identity is actually vampires. They were bitten by the zombie Wang Jiangchen (played by Simon Yam) at the same time sixty years ago. Therefore, they are immortal and depend on each other as father and son, and only survive by stealing blood from the hospital. They become friends with their neighbors Wang Zhenzhen (played by Yang Gongru) and Ma Xiaoling (played by Wan Qiwen) who live in the same building. They also learn that Ma Xiaoling is actually a descendant of the exorcist dragon clan, who is cursed by the family and cannot cry for men, so she cannot fall in love. During their time together, Wang Zhenzhen gradually falls in love with Tianyou, and Ma Xiaoling also tries hard to match the two. Tianyou can't bear to hurt the kind Zhenzhen, but he knows in his heart that he and Ma Xiaoling are attracted to each other. A passionate pursuer of Zhenzhen appears in their lives. His name is Yamamoto Kazuo (Chen Qitai), but his real identity is Tianyou’s old enemy who turned into a zombie at the same time sixty years ago. It seems that things belonging to two eras and two generations are happening to the same group of people. The secret of Kuang Tianyou’s identity is also revealed, and Ma Xiaoling needs to join forces with him to fight the enemy.
