The Mimic is a 2017 (Hangeul: 장산범, tr. Jangsanbeom) South Korean horror film written and directed by Huh Jung, and starring Yum Jung-ah and Park Hyuk-kwon. It was released on August 17, 2017.
 A couple argues while driving in the mountains at night. The man hits a dog and brings its body to the trunk. Inside the trunk is his wife, bloodied and bound. In the woods, the man smashes open a brick wall as his wife slowly dies. He puts the bodies inside and turns to leave when they hear the disembodied voice of his dead wife calling him.
 Hee-yeon, Min-ho, and their little daughter Joon-hee move to Mt. Jang with Joon-hee's grandmother, who is senile, hoping it will improve her condition and so Hee-yeon and Min-ho can heal after their young son went missing five years ago. The grandmother hears her dead sister's voice calling her from the woods. Two children come in search of their dog, the one killed in the car accident from the beginning. The kids hear their dog barking and follow the sound to the brick wall. The girl is pulled through the hole in the wall by an unseen force but escapes.
 The kids run to Hee-yeon and Min-ho for help. Hee-yeon encounters a little girl in the woods but is drawn away by the kids and her husband, who enters the hole and finds a bolted door. When he opens it, a mutilated woman falls through, dead. They report it to the police. That night, the mysterious girl appears at their door and Hee-yeon takes her in. The girl calls her "Mom", mimics Joon-hee's voice, and says her name is also Joon-hee. Hee-yeon discovers signs of abuse on the girl's body. Min-ho is unsettled by the girl and Hee-yeon's refusal to get over their son and move on. The police track down the man from the beginning, who now hears voices and has eye problems. He is killed by the entity. The detective discovers that Mt. Jang has many missing persons cases, all of whom reported hearing voices of dead loved ones before disappearing. He also finds an old photo from the 1980s, revealing a man with the same little girl Hee-yeon has taken in.
 The grandmother covers the house's mirrors in tape, as that is how the entity comes through. She succumbs to her sister's voice and follows it to the cave behind the brick wall. Min-ho goes to search for her and disappears as well. Hee-yeon goes to their neighbor, a blind woman, for help. The woman explains that long ago, there was a shaman in these parts who had a little daughter, the same girl who came to Hee-yeon. The shaman, a social outcast, willingly served a malevolent spirit residing in Mount Jangsan called the Jangsan Tiger to gain power. The shaman would abuse his daughter and slowly became possessed by the entity. He sacrificed his own daughter to appease the tiger's spirit. Now cursed, both he and his daughter imitate voices to lure in victims and sacrifice them. The woman warns Hee-yeon not to trust the little girl, and that those who give in lose their eyesight.
 Jangsanbum attacks Joon-hee; Jangsanbum's daughter saves her. Hee-yeon shuts Joon-hee in her room, warning her not to trust any voices and to call the detective if she does not return. Hee-yeon then asks Jangsanbum's daughter to guide her to Min-ho. In the cave, they are chased by Jangsanbum into an area full of mirrors. Hee-yeon is driven into panic by voices and almost gives in until Min-ho, now blind, breaks the largest mirror that Jangsanbum's spirit is in, destroying the spirit as well as the shaman. Hee-yeon, weakened by the little girl mimicking her missing son's voice, goes blind. At the cave opening, unable to resist her son's voice, Hee-yeon turns back, despite Min-ho begging her not to trust it and that it is not their son. She returns to the little girl and the two go back into the cave. Min-ho stumbles back outside and is found by the detective.
 The plot is inspired by the South Korean urban legend of the Jangsan Tiger, a man-eating creature that roams around Jangsan, a mountain in the city of Busan. It is rumored to have sharp teeth and white fur and moves swiftly through mountains and lures people by making a sound that resembles a woman's wail.
