When the story begins, Cal and Becky pull over on the side of a country road when she begins to feel carsick. After they hear the voice of a child screaming in the grass next to their car — followed by a woman's voice calling after him — they decide to see if they can help.
While walking amongst the tall grasses and trying to locate a disembodied voice is challenging enough, Becky and Cal also have to deal with further disorientation: They lose track of each other, and quickly become lost. When Becky calls out for Cal, at first it sounds like it's coming from one side of the field, and then the other. This, naturally, leads them to both panic and begin to frantically search for one another.
During their separation, Becky encounters Ross, who says he'll lead her out of the field; Tobin ends up finding Cal — who, in turn, stumbles across Travis, mourning over Becky's decomposing body, despite the fact that Cal and Tobin heard her crying for help only a few moments earlier.
To say the already-weird situation gets even weirder from that point forward is an understatement. When the characters eventually all meet up, they realize that something is amiss. Travis, for example, seems to have both entered the field of grass before Cal and Becky, but also after them. It all starts to feel even more sinister when it becomes apparent that the grass has a mind of its own, and seems to be manipulating the characters into further confusion and chaos.
