Seok Hwan is full of justice and has no patience with injustice. Due to his fiery personality, he`s been unemployed since graduating college. He has no dream or hope, and has been alone since his father died when he was a child. One day, he sees loan sharks harassing his neighbour, high school student Ye Rin, who lives next to him. Seok Hwan fights them off - and is killed. Three days later, he wakes up in his apartment, alive again. Seok Hwan realizes he resurrects three days after every death, no matter what, and uses this ability to fight against evil.
