500 years ago in the Joseon Dynasty, the Flute of the prophecy has fallen into the evil hands of the goblins, propelling the world into a whirlwind of disorder. The ancient Taoist wizards turn to the greatest ascetics of their time, the Master (Baek Yoon-Sik) and Hwadam (Kim Yoon-Seok) for help in vanquishing the goblins and trust each wizard with one half of the Flute. Meanwhile, the Master's rascal student Jeon Woochi (Gang Dong-won) tricks the king with the art of transformation and creates a fiasco, which makes the three Taoist wizards and Hwadam visit the Master. But they find the Master murdered and his half of the Flute missing. Woochi is framed for the murder, and as punishment, he and his trusty dog Chorangyi (Yoo Hae-jin) are imprisoned inside a scroll by the wizards.
Seoul, 2009. For some strange reason, goblins that had been sealed up in the past begin to appear one by one, wreaking havoc on the city. The three Taoist wizards had been enjoying their years of retirement as a priest, a monk, and a shaman, while Hwadam has long disappeared to polish his Taoist art. After much discussion, the three wizards unseal the scroll and call forth Jeon Woochi and Chorangyi. Being offered freedom in return for catching the goblins, Woochi sets out on his task. But what began as a hunt for goblins slowly turns into Woochi's sightseeing expedition of the modern-day world. And to top it off, he meets a woman with the same face as the one that had captivated him so many centuries ago (Im Soo-Jung). Together with Seo In-Kyung (his new, yet old love), Woochi begins his adventure.
Unbeknownst to anyone, Hwadam has been secretly releasing the goblins to distract the Taoist wizards away for his motive. Having taken the Flute for himself, Hwadam intends to release the Arch God who has been imprisoned in a human body. He discovers In-Kyung whom he suspects is the Arch God. After failing to make it in the acting business partially due to her innocent and cute looks, Hwadam uses his powers and changes her into a self-assured and savvy actress. The director having been frustrated with his chosen actress's behavior, takes notice of In-Kyung and has her cast as his new leading lady. Both Woochi and Chorangyi discover Hwadam's true motive in murdering the Master to steal the flute for himself.
