One is the most inconspicuous lame boy in the General's Mansion. He is clumsy and as timid as a mouse. His catchphrase is "Dead leg, run!".
One is a violent and moody young general who enjoys tormenting his subordinates, especially the lame boy who runs away when scared.
One is the top stalker of the enemy's spy organization "You Tan", codenamed "Tan Ying". The right leg is a disguise, with superb martial arts skills and a tough mind. Carrying a blood feud (for example, the whole family died because of the hero's father's defeat in the war), working undercover just to steal the border defense map.
One is carrying the royal secret order and secretly investigating the huge conspiracy between the DPRK and the enemy in collusion. His father's death in war and the decline of his family left him traumatized, and he used perversity to cover up his loneliness and vigilance. His evil is both temptation and protection.
The two explore the truth in the storm in a game of cat and mouse. The general finally ushered in flames and new life after chasing his wife in the crematorium.
