No Blade of Grass (1970) Timeline Explained – Every Event in Order

Pirrie shoots Sturdevant after John explains the gravity of their situation, the grass disease is devastating global food supplies and causing societal collapse. When Pirrie holds them at gunpoint, John persuasively argues that old societal rules no longer apply and that they need weapons to survive. Pirrie decides that Sturdevant, who refused to help despite the crisis, is a liability who might alert authorities or rob them later. He kills Sturdevant and immediately decides to join John's group, seeing them as his best chance of survival.

Foreshadowing: Pirrie's quick decision to kill and join strangers foreshadows his ruthless survivalist mentality throughout the journey.

The Army roadblock is part of the government's desperate attempt to maintain order during the crisis. The soldiers refuse to let them pass, likely because the authorities are trying to control population movement and conserve resources. With no permits and no time to negotiate, since the situation is deteriorating rapidly, John and Roger realize they must eliminate the soldiers to continue their journey northward. The brutal necessity of killing armed forces illustrates how far society has collapsed.

Foreshadowing: This first major act of violence against authority figures sets the pattern for the group's moral descent throughout the film.

While John's car is stopped at a railroad gate, three men abduct his wife Ann and 16-year-old daughter Mary. They are taken away and raped by the attackers. John and the others eventually locate them, killing two of the attackers, but one man escapes into the chaos of the collapsed world. This horrific event deeply scars the family and intensifies the group's desperation and paranoia.

After being robbed of their vehicles and weapons by vigilantes, John's group finds themselves unarmed and vulnerable with fifty miles still to travel. They encounter an isolated farmhouse and realize the farmer and his wife have guns, essential for survival in the dangerous new world. Faced with the choice of continuing unarmed or taking what they need by force, they choose the latter, killing the couple and seizing their weapons. This act represents the complete moral collapse of the group, reducing them to the very violence they fear from others.

Foreshadowing: The cold calculation of killing innocent farmers for their weapons mirrors the earlier robberies and sets the stage for John's final assault on his own brother.

Clara attempts to seduce John in the abandoned factory, likely seeking to secure protection and status by aligning with the group's apparent leader. Her husband Pirrie discovers the encounter and, believing she is trying to displace him or undermine his position, shoots Clara dead. The murder reflects the brutal power dynamics among survivors, trust is nonexistent, and even intimate relationships are viewed through the lens of survival and control.

Foreshadowing: Clara's death removes the last check on Pirrie's violent impulses and clears the way for his growing influence over the group, particularly with Mary.

In the brutal new world, Mary is a 16-year-old girl who has witnessed extreme violence, including her own mother's rape. She gravitates toward Pirrie because he represents physical strength and ruthlessness, the qualities needed to survive. Believing he can protect her, Mary forms an uneasy bond with the man who murdered his own wife, demonstrating how desperation rewires moral judgments and creates strange allegiances.

Foreshadowing: Mary's relationship with Pirrie complicates the final confrontation, as she is aligned with the man who will kill her uncle David.

David explains privately to John that his valley can only support a limited number of people and he cannot risk admitting such a large, desperate group that might deplete resources or bring violence. He suggests John slip away with just his immediate family and Roger in the night, essentially abandoning the others who traveled with them. This pragmatic calculation reveals how scarcity has corrupted even family bonds, David would rather save himself and a few others than honor the kinship with his brother.

Foreshadowing: David's refusal directly prompts John's decision to launch a night assault, prioritizing his group's survival over familial loyalty.

After David privately tells John he cannot admit the full group, John faces an impossible choice: abandon the people who trusted him and survived with him, or seize the valley by force. Rather than sneak away as David suggested, John launches a night assault to capture the valley for his entire group. During the fight, Pirrie shoots David at the machine gun position, and Pirrie himself is killed in the melee. John succeeds and takes leadership of the valley, having betrayed and killed his own brother to secure safety for his family and followers.

Foreshadowing: This tragic climax fulfills the film's dark progression, from desperate survivors to violent usurpers, becoming the very threat they fled from.

The escaped rapist later resurfaces as a member of a motorcycle gang that attacks John's group on the road. Ann recognizes him among the riders, triggering the violent confrontation. The gang mounts several attacks, resulting in casualties on both sides. This encounter represents the film's theme of inescapable violence, the horror from the train crossing returns to haunt them, demonstrating that past atrocities cannot be outrun in a collapsed world.

The film establishes through its opening montage that pollution triggered a virulent new disease that attacks all grass family crops, wheat, rice, and maize. The pathogen spreads rapidly from Asia to Africa, Europe, and South America, causing widespread crop failure, famine, and societal collapse. This biological catastrophe is the root cause of all the violence and chaos that follows, as billions face starvation and governments lose control.

Foreshadowing: The montage's depiction of China unleashing nerve gas on its own people foreshadows the moral compromises and extreme violence that will characterize the survivors' journey.
