Known for her impressive emotional range and captivating screen presence, Kim Hye-yoon now steps into the eerie world of psychological horror — and fans can’t stop talking about it.

In the upcoming South Korean horror film Salmokji: Whispering Water, Kim Hye-yoon plays Su-in, a determined and no-nonsense producer leading a production team to a remote reservoir. What begins as a routine reshoot quickly spirals into terror after the crew spots a mysterious figure lurking near the deep waters. As fear tightens its grip, Su-in finds herself battling not just the unknown presence surrounding the reservoir but also her own unraveling psyche.

The newly released stills capture Kim Hye-yoon standing alone at night near the shadowy water, her expression tense and haunted. In one image, the faint glow of red lights behind her intensifies the unsettling mood, while another shows her drenched in fear and confusion, perfectly embodying Su-in’s psychological descent. The transformation is striking — gone is the bright, youthful charm audiences adore, replaced by raw vulnerability and survival instinct.

Directed by Lee Sang-min, the film promises an atmospheric blend of suspense, mystery, and psychological horror set against the haunting backdrop of an isolated reservoir. The storyline follows a production team trapped in escalating dread as they confront something far more sinister than they ever imagined. Su-in, who believes only in what she sees, is forced to question reality itself as terrifying events unfold.

Fans are especially excited to see Kim Hye-yoon challenge herself in a genre she has never headlined before. Her ability to portray layered emotions suggests that Salmokji: Whispering Water could mark a powerful turning point in her career. The actress has consistently impressed viewers with her versatility, and this chilling role may solidify her status as one of the most dynamic performers of her generation.

With its ominous tone, suspenseful premise, and Kim Hye-yoon’s gripping transformation, Salmokji: Whispering Water is already shaping up to be one of the most anticipated Korean horror films of 2026. As anticipation builds toward its April release, audiences are eager to witness just how far Su-in will go to survive the whispers rising from the depths.
