The story revolves around siblings Becky (Laysla De Oliveira) and Cal (Avery Whitted), who are traveling through rural Kansas when they hear a young boy’s cries for help coming from a vast field of tall grass. They venture into the grass to rescue him but soon find themselves disoriented and unable to escape. The grass seems to have a supernatural, malevolent force that distorts time and space, trapping them in a nightmare.

As the characters struggle to find a way out, they encounter others who are also lost in the field, including a mysterious man named Ross (Patrick Wilson), whose behavior becomes increasingly disturbing. The movie explores themes of disorientation, isolation, and the horrors lurking within the unknown.

In the Tall Grass is known for its unsettling atmosphere, eerie visuals, and psychological tension, though it received mixed reviews for its slow pacing and abstract narrative. It offers a blend of supernatural horror and existential dread, with plenty of twists and turns typical of Stephen King’s style.
