Ahead of its release, Sleep unveiled new stills featuring the leads Lee Sun Kyun and Jung Yu Mi.
Directed by Yoo Jae Sun, Sleep tells the story of Hyun Soo (Lee Sun Kyun) and Soo Jin (Jung Yu Mi), a blissful couple whose life is turned upside-down by Hyun Soo's peculiar behavior when he falls asleep.
The stills capture a range of emotions, from the couple warmly embracing each other to the nerve-racking tension of their confrontation with the eerie terrors that haunt their sleepless nights.
As Hyun Soo undergoes a bewildering change upon falling asleep, acting like a stranger, Soo Jin grapples with her own trepidation. But they find solace in each other, endeavoring to decipher the mystery behind Hyun Soo's behavior.
Sleep marks the fourth collaboration between Jung Yu Mi and Lee Sun Kyun.
Director Yoo Jae Sun commended the two lead actors, asserting that Sleep would have been impossible without Jung Yu Mi and Lee Sun Kyun, lauding their remarkable performances.
Sleep is set to grace theaters on September 6th.
