In the apocalyptic world, the terrifying zombie king "Zero" has devoured tens of thousands of humans and is a nightmare for all survivors. After a nuclear explosion, he traveled to the modern city of 2024 and possessed a divorced single father with a child. When his five-year-old daughter Tangtang opened her big eyes and called him "Daddy", he almost instinctively pounced on it... And took a bite. In order to survive in this strange world, the former zombie king had to learn how to prepare milk powder, hold parent-teacher meetings, and apologize to the kindergarten teacher. But when his daughter was bullied, he subconsciously showed his fangs, and the community security guard fainted on the spot; when the drug dealer fled, he casually stopped the car with his bare hands, and the surveillance camera captured the superhuman scene. Faced with the pursuit of stalkers and the suspicion of the police, Zero just wanted to ask: Which is more difficult, being a dad or being a villain?
