After hearing a child screaming for help from the green depths of a vast field of tall grass, Becky, a pregnant woman, and Cal, her brother, park their car near a mysterious abandoned church and enter the field, discovering that they are not alone and, for some reason, they are unable to escape a completely inextricable vegetable labyrinth.
Unfortunately the movie In the Tall Grass is not yet available on HBO Max.
