500年前的朝鲜时代。

仙界里法术高強的天冠大师和花潭（金允石饰）負責收封作恶多端的妖怪，而天冠大师的得意弟子--精通遁甲、移形和隐身等多种道术的田禹治（姜东元饰）平日爱耍小聪明闯祸，一天，他引起凡间大骚动，花潭打算找天冠大师兴师问罪，却发现天冠大师不知所踪。田禹治和他的死党楚铃儿（刘海镇饰）被众神仙认为是杀害天冠大师的嫌犯，因此两人遭封入一幅画轴中。

500年後的首爾。

原本被封印在画中的妖怪竟出来在人间兴风作浪，过去的那些神仙们都已退隐为现代的神父、和尚。他们再次聚集起来找花潭商量对付妖怪的办法，但花潭早与大家失去联系。众神仙只好將封印了的田禹治和楚铃儿放出要求二人将功赎罪。但生性自由风流的田禹治看到新鲜繁华的现代非常着迷，很快将抓妖怪的使命抛诸脑后忙于四处玩逛，更巧遇500年前自己一见钟情的女子长得一模一样的徐寅璟（林秀晶饰），开始了浪漫的爱情游戏。一方面，得知田禹治二人被放出来的花潭勃然大怒，和众神仙对敌了起来，决定要杀死田禹治等人……

Begins in the Chosun Dynasty in 1509 and involves a trio of Taoist wizards, a magician named Woochi (Gang Dong-won)and his dog turned man, a corrupt king, evil goblins, and a prophetic pipe everyone is after. Eventually Woochi becomes sealed inside an ancient scroll for a crime he did not commit.

Jumping ahead to the year 2009, the wizards are called out of peaceful retirement as goblins start appearing in modern Korea to wreak havoc all around. The trio call on Woochi, who is released from his ancient scroll entrapment, in to save the day. Problem is Woochi, a kind of anti-superhero, becomes more interested in sight-seeing and womanizing in modern day Korea .
