The rising star of Taekwondo, Zhi Yao, retires due to injury and becomes addicted to gambling. To pay off his debts, he is coerced by evil forces and forced into prison to work as a prison administrator and take care of the prison boss Chihuahua. He thought he was the most unfortunate soul, but in prison he realizes how miserable his colleagues are. These newcomers receive shocking ridicule every day—they are beaten during riot control, sprayed with shit during prosecution, and prisoners even threaten to commit suicide. The administrator also ironically has to bow down to and placate the prisoners, almost subservient to them. On top of the suffocating rigid system, Zhi Yao practically lives on the brink of death as the instructor Jiang Yi Jie keeps an eye on the special relationship between Zhi Yao and Chihuahua. To think that corporate slaves are more imprisoned than the prisoners themselves! But in the absurd and cruel days, Zhi Yao and his companions gradually develop chemistry, friendship, and love, tiding each other through the tough times and finding true meaning in this line of work.
