When a young deaf woman nearly rescues the prey of a serial killer late one night, a harrowing game of cat and mouse is set in motion. The taut twists go from 0 to 60 in no time flat, between colorful character development and nail-biting suspense. Jin Ki-joo (Little Forest) gives a tour-de-force performance as the tenacious heroine who must negotiate new dangers at every turn. The clever conceit of the film's innovative premise, a pervasive sense of dread and implicit social critiques—the failure of the police to offer protection being just one glaring example—all boil over into a dynamite edge-of-your-seat thriller not to be missed.
