The 12 Zodiac Deities (Bangjeongsa), who have transformed into human form, use the divine scale known as 'Cheonpyeong' to measure the weight of the victim's pain, 'Honggo,' and the perpetrator's pain, 'Heukgo,' to administer punishments accordingly.
"The scale must be true and just, and the weight of the sin and the punishment must be equal."
A fantasy human drama about the 'sins and punishments' of humans, as carried out by the 12 Bangjeongsa who punish human sins by the command of the heavens!
