The Restless is a 2006 South Korean period fantasy film directed by Jo Dong-oh, starring Jung Woo-sung and Kim Tae-hee.

In ancient Korea, Yi Gwak is a former chief of a disbanded elite ghost-hunting military unit who makes a living as an itinerant demon hunter.

Yi Gwak also encounters his former mentor Ban-chu, who is revealed to be masterminding a demonic rebellion in Midheaven along with other members of their former elite unit in order to invade the living world and take revenge for the injustices done to them when they were alive.

While initially reluctant to fight his former comrades and his mentor, Yi Gwak chooses to protect So-hwa and finds himself at odds with Ban-chu and his former brothers-in-arms.

The first soundtrack, Memory of The Restless OST, was released as an EP on Dec 14, 2006 by CJ Entertainment.
