Having died unexpectedly, firefighter Ja-hong is taken to the afterlife by 3 afterlife guardians. Only when he passes 7 trials over 49 days and proves he was innocent in human life, he's able to reincarnate, and his 3 afterlife guardians are by his side to defend him in trial.—Lotte Entertainment

When the fireman Kim Ja-hong dies during a rescue operation in a fire in a building, his guardians Kangrim, Haewonmaek and Dukchoon guide him to the afterlife. They explain that they will defend him in seven trials with seven gods in seven hells along forty-nine days to disclose how he spent his life. Ja-hong, who is considered a model citizen, will reincarnate if his guardians are well-succeeded in their defense. However, there are disturbances in the afterlife caused by a Revengeful Spirit and Kangrim goes to the World of the Living to investigate what is happening. Meanwhile the prosecutors find problems in the relationship of Ja-hong and his mother and brother and Haewonmaek and Dukchoon are surprised by the discoveries.
