The story begins with a king in the afterlife who is trying to help a vengeful spirit, Su, cross the gates of the afterlife. However, Su is told that he cannot be reincarnated because he lost the right due to being a god of inventiveness. The king proposes a deal where Su can prove that he became a vengeful spirit due to an unjust death, and if successful, he will be given the opportunity to reincarnate again.
Su accepts the deal and is tasked with getting rid of the god of family protection, Zion, who has been protecting a complete for several years. Su and his companions go to Zion's house, where they encounter Zion's grandson, who is the only person he cares about. Zion tells them that he will only give up his soul after his grandson enters school.
Throughout the story, the companions learn more about Zion's past life as a warrior who wore a white scarf to cover his face, earning him the nickname "White Beast." They also learn about his relationships with his adoptive brother and his friends, who ultimately led to his death.
As the story unfolds, the companions face various challenges, including dinosaurs and a final judgment in the volcano of murderers. Ultimately, Zion confesses to killing his friend and asks for forgiveness, which leads to the god of death declaring him innocent and ordering him to reincarnate.
The story concludes with Zion being reincarnated and his grandson being taken care of by the guardians. The king asks Zion's grandson to become a guardian, and the movie ends with the companions looking like Zion, implying that they may be his reincarnated form.
