As the deceased soul Ja-hong and his three afterlife guardians prepare for their remaining trials for reincarnation, the guardians soon come face to face with the truth of their tragic time on Earth 1,000 years earlier.

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.

Jobless, besieged by creditors, and abandoned by his wife, the once silver medalist Tae-shik has sunk to street hustling, becoming a human punching bag. Meanwhile, young Sang-hwan's delinquent ways land him behind bars. Both men look to boxing to turn around lives gone astray, aiming for the amateur title, ultimately pitting them against each other, but more importantly, against themselves.

On 31 January 1968, 31 North Korean commandos infiltrated South Korea in a failed mission to assassinate President Park Chung-hee. In revenge, the South Korean military assembled a team of 31 criminals on the island of Silmido to kill Kim Il-sung for a suicide mission to redeem their honor, but was cancelled, leaving them frustrated. It is loosely based on a military uprising in the 1970s.
