Undercover agent Zhao Huairen travels through time and becomes the leader of a bandit stronghold. All he wants is to leave the mountain in peace and live as a wealthy landowner! But one night, he discovers Prince You, who has fallen from his horse and died. The two men look exactly alike, and the imperial edict and the prince's gold token both end up at the stronghold. To save the lives of everyone in the stronghold, he follows the plan devised by the frail second-in-command and impersonates Prince You on his way to Youzhou. By pretending to have lost his memory after falling from a horse, he fools everyone in the prince's residence and infiltrates officialdom with a band of bandit brothers, each possessing extraordinary skills. He only wants to find a chance to escape, but somehow keeps accomplishing extraordinary feats, earning praise from the common people as the wisest prince of all time! Thus begins a hilarious, unconventional political power struggle full of outrageous contrasts.
