Hyun-su and Soo-jin are newlyweds. Seemingly out of nowhere, he starts talking in his sleep. “Someone’s inside.” From that night on, whenever he falls asleep, he transforms into someone else with no recollection of what happened the night before. Soo-jin is overwhelmed with anxiety that he’d hurt her family while she sleeps and can barely sleep a wink because of this irrational fear. Despite sleep treatment, Hyun-su’s sleepwalking only intensifies, and she begins to feel that her unborn child may be in danger…

What the Critics Are Saying

“It’s an impressive first feature from Jason Yu, who is as adept at wielding the sly observational comedy of the film’s first half as he is at ratcheting up the claustrophobic tension later on.”
– Wendy Ide, Observer (UK)

“Jason Yu crafts a twisty delight that leaves you doubting what you’re seeing and wondering what to believe right till the last moment.”
– Alissa Wilkinson, Vox

“A phenomenal debut, a movie that rises to an incredible climax that should have people talking.”
– Brian Tallerico, RogerEbert.com
