Human Nature (2002) Timeline Explained – Every Event in Order

Lila returns to civilization at age thirty because she experiences a intense sexual desire and loneliness that she cannot satisfy living as a hermit in the forest. Despite writing a best-selling memoir celebrating her wild, natural life, she ultimately decides she needs human companionship and a partner who can understand her complexity. This drives her to shave her body hair and reenter society to find connection.

Foreshadowing: Earlier in the film, Lila's memoir celebrates living 'naked, wild, and free,' but the story reveals this philosophy cannot fully satisfy her deeper need for intimacy.

Lila encounters Puff, a man who has lived his entire life raised by wolves in the forest, while hiking. Drawn to him because of their shared wild nature, she discards her clothes and pursues him through the woods. During the chase, Puff falls from a tree branch and is knocked unconscious. Lila then brings him to Nathan Bronfman's laboratory, where Nathan decides to keep him as a subject for his experiments on conditioning wild subjects to behave like civilized humans.

Foreshadowing: Lila's own history of leaving civilization to live wild establishes her attraction to others who exist outside social norms.

Nathan Bronfman is a psychologist obsessed with testing the boundaries between civilization and wild instinct. He previously experimented with teaching table manners to mice and sees Puff as the ultimate opportunity to prove that even a completely wild human can be trained to adopt the behaviors and etiquette of civilized society. His goal is to demonstrate that social behavior can be imposed through conditioning, regardless of one's natural state.

Foreshadowing: Nathan's work with mice, mentioned when he first meets Lila, foreshadows his ambition to replicate similar results with a human subject.

Nathan begins an affair with Gabrielle, his French-accented assistant, despite already being in a relationship with Lila. The affair represents Nathan's underlying conflict between his scientific ambitions and his personal desires. Gabrielle represents a different kind of connection, one that doesn't require the emotional complexity Lila brings. The affair destabilizes the trio's dynamic and accelerates the deterioration of Nathan and Lila's relationship, ultimately influencing the tragic events that follow.

Foreshadowing: Early in their collaboration, Gabrielle's mysterious background and fake French accent hint at her manipulative nature.

Lila decides to 'undo' Puff's training and return him to his natural state because she becomes uncomfortable with Nathan's exploitation of Puff. Having initially supported the experiment, she grows to see the conditioning as a form of oppression that strips away Puff's authentic self. She believes his wild, uninhibited nature should be preserved rather than erased. Her decision also reflects her own internal struggle between her attraction to wildness and her need for civilization.

Foreshadowing: Lila's own journey from wild living to civilization and back again mirrors what she hopes to achieve for Puff.

Nathan confronts Lila and Puff in the forest, intending to retrieve Puff and continue his experiments. During the confrontation, Puff, acting out of instinct, fear, and a misguided sense of loyalty to Lila, attacks Nathan and kills him. The death occurs in a moment of chaos where Puff's wild nature resurfaces violently, demonstrating the failure of Nathan's conditioning experiment. This tragic outcome stems from Nathan's refusal to accept that Puff's wild instincts cannot be permanently suppressed.

Foreshadowing: Nathan's earlier concerns about Puff's inability to control his sexual urges hint at the volatility lurking beneath the trained exterior.

Lila turns herself in to the authorities despite not being the one who killed Nathan. She takes responsibility because she feels guilty for having brought Puff into Nathan's world and for the chain of events that led to the murder. By surrendering, she also ensures that Puff will be allowed to testify about humanity's 'waywardness', her plan to use his unique perspective as a statement about civilization versus nature. Her surrender represents both penance and one final act of advocacy for the wild life she believes in.

Foreshadowing: Lila's earlier decision to return Puff to the forest sets in motion the confrontation that leads to Nathan's death.

After Nathan's death and Lila's surrender, Puff briefly returns to the forest but then emerges to accompany Gabrielle into the city. They drive away together to eat, leaving the forest behind. The ending deliberately leaves ambiguity about whether Puff is truly free or if he's simply entering another form of 'civilization' with Gabrielle. This ambiguous conclusion reinforces the film's central question about whether humans can ever truly escape the pull of society.

Foreshadowing: The earlier hint that Gabrielle's French accent was fake suggests she may have her own hidden agenda in befriending Puff.

The closing credits feature William of Ockham discussing intuitive cognition and Francis Bacon explaining inductivism, essentially how knowledge forms from experience and observation. These passages frame the entire film as an experiment in understanding human nature. The film questions whether we are born civilized or become so, and whether knowledge of 'civilization' truly changes our innate instincts. The philosophical framing invites viewers to interpret the events as an exploration of how humans form beliefs about nature versus nurture.

Foreshadowing: The entire narrative structure, told through multiple unreliable perspectives, mirrors the film's interest in how we construct knowledge.

Despite Nathan's conditioning, Puff cannot completely suppress his wild instincts, particularly his powerful sexual urges. During the tour meant to showcase his 'civilized' behavior, Puff secretly drinks heavily and patronizes prostitutes, revealing the fundamental gap between trained behavior and innate desire. This struggle represents the film's central theme: that wild nature cannot be permanently erased through external conditioning, no matter how sophisticated the training methods.

Foreshadowing: Nathan's earlier experiments with mice likely encountered similar failures in completely overriding natural instincts.

Nathan names the wild man 'Puff' after Gabrielle's childhood dog. This naming choice reflects the film's treatment of Puff as more of an experimental subject than a person with an identity. The name also carries ironic weight, 'puff' suggests something light and insignificant, which contrasts with the profound philosophical questions Puff's existence raises about humanity.

Foreshadowing: The casual naming hints at Nathan's view of Puff as a scientific curiosity rather than a human being with rights.

Lila has a rare hormonal imbalance that causes hair to grow all over her body. This condition is what initially drives her to the freak show and later compels her to live in the forest where she can exist without judgment. When she returns to civilization, she shaves her hair to appear 'normal' and attract a partner. Her condition serves as a physical manifestation of the film's exploration of what society considers 'natural' versus 'civilized,' and the lengths people go to conform.

Foreshadowing: Lila's hair condition prefigures her attraction to Puff, both are 'wild' by societal standards.
