Plot
A pregnant Becky and her brother, Cal DeMuth, are traveling to San Diego. They hear the cries for help from a young boy named Tobin, who is accompanied by his mother, Natalie. Concerned, the siblings enter but quickly get separated and find that their distance changes unnaturally. They decide to leave but can't find the road. Becky encounters Tobin's father, Ross, who tells her to stay close and not to lose sight of him, but she does so. Cal stumbles across Tobin, holding a dead crow. Tobin claims the grass won't move dead things and buries the bird in the path, telling Cal that rock told him Becky would die soon. When Tobin leads Cal to a rock in the field and tells him to touch it, he hears Becky's scream before a ghost attacks him.
The father of Becky's child, Travis, arrives looking for the siblings. He investigates the field, stumbling across Tobin, who implies they know each other and leads him to Becky's corpse.
Tobin arrives at a nearby church with his parents. He and Freddy, the family dog, hear Travis shouting Tobin’s name from the grass. Freddy is drawn in, which leads Tobin, Natalie, and Ross to follow and get separated. With the family panicking, Becky and Cal re-enter the grass as Tobin states Freddy died. Knowing the grass's trait, Travis, Becky, and Cal move toward Tobin, and all four find each other. Travis tells Becky and Cal that they have been missing for two months. It is also revealed that Travis originally was not interested in being a father and asked Becky to abort their baby, which she refused. As a result, Becky and Cal traveled to San Diego to meet a family interested in adopting her baby when it was born as she did not feel ready to be a single parent. Travis expresses regret and now wants to be part of his child and Becky's lives.
The group spots a building in the distance. Becky receives a phone call from someone warning them not to keep making the same "mistake". The grass seemingly enters Becky's uterus, and she passes out, only to be revived by Ross, who then reunites with Tobin and says he will show them out. Ross leads them to the rock, where they are confronted by Natalie who warns them not to touch the rock, and that Ross is dangerous, telling the others to decide to leave. Travis attacks Ross who then breaks his arm and crushes Natalie's head. Ross claims the rock showed him the truth and the way out, but he does not want to leave.
Becky, Cal, Travis, and Tobin reach the building, and while scouting, Travis and Cal discover that Freddy has managed to escape the field via a "hole" that leads to the road. Cal lets go of Travis as he slips, causing him to fall off the roof. Tobin flees into the field when Ross follows them to the roof. The two follow Tobin, but Becky refuses to leave Travis and goes back as Cal flees, Cal is strangled to death by Ross. It is revealed they are in a time loop, with Cal permanently being hunted by an insane, possessed Ross in the grass. Travis survives and searches for Becky.
