Young couple Hyun-su (Lee Sun-kyun) and Soo-jin (Jung Yu-mi) are about to become new parents when, one night, heavily pregnant Soo-jin wakes up to her husband’s first act of parasomnia. From then on, in the weeks and months that follow, Hyun-su’s behaviour gets increasingly more disturbing, transforming into someone unrecognisable once he falls asleep. After their child is born, Hyun-su’s actions grow more and more grotesque and bizarre, and Soo-jin begins to fear the worst.

Debut director Jason Yu, who was once the assistant director for Academy Award-winning Bong Joon Ho, brings audiences a clever, well-crafted and genre-bending thriller that rachets up a creeping horror towards its fantastically bonkers finale.

"A directorial debut of poised peril that should inspire both laughs and a few sleepless nights." - Nick Schager, The Daily Beast
