Nami Matsushima (Meiko Kaji) is locked up and bound in underground solitary confinement, a stark picture of control and deprivation. She manages a quiet, stubborn defiance by fashioning a weapon from a spoon, grinding it against the rough concrete floor with her teeth as a small rebellion against the system that confines her. The prison’s chief warden, Goda, Fumio Watanabe, is on the verge of a promotion, a detail that underscores how reward and cruelty mingle within the prison walls.

When an inspector visits, Matsushima is allowed out for a single day. In the tense, spotlighted moment of scrutiny, she launches a shocking, sudden attack on Goda, leaving a jagged scratch across his face and shattering the procedural calm of the facility. The other inmates erupt in riotous anger, but the guards act with practiced efficiency, suppressing the unrest and restoring a fragile order.

The aftermath brings a brutal punishment: the inmates are sent to an intensive labour camp, a harsh measure designed to crush any spark of resistance. To reaffirm dominance and deter any future uprising, Goda orders four guards to publicly threaten and rape Matsushima. The brutality is not just punitive; it’s a calculated spectacle meant to erase the prisoners’ humanity.

Matsushima returns from the labour camp to a van carrying six other prisoners, among them Oba (Kayoko Shiraishi). The ride is a gauntlet of violence—Matsushima is beaten into near lifelessness, and when the guards think she is dead, she awakens with a cold, lethal resolve. She strangles one guard, and Oba and the others overpower another as they blow up the van. Goda sees the wreckage and dispatches search parties to hunt down the fugitives.

The escape leads to an abandoned village, where Oba’s confession lands like a punch to the gut: after discovering her husband’s infidelity, she drowned her two-year-old son and stabbed her unborn baby. In the village, the prisoners encounter a mysterious old woman wielding a dagger; a surreal sequence follows, revealing the prisoners’ accumulated sins as the old woman dies, her body turning into leaves and blowing away with the wind. Before dying, she hands Matsushima a knife, a symbolic tool for the road ahead.

From the village, the group moves to a nearby town to steal clothes and disappear into the night, sheltering in an abandoned hut. One of the prisoners, Haru (Yukie Kagawa), quietly slips away to her own home, where she reunites with her son but also discovers two jailers. They offer to free Haru if she reveals the others’ locations. Distraught, Haru withdraws, but a guard shadows her while another returns to Goda. Matsushima intervenes, killing the pursuing guard, and in the skirmish, a fellow prisoner is accidentally shot and dies.

A sightseeing tour comes through the area, and violence erupts again as three aggressively predatory men from the group rape another prisoner and are left to die. The other prisoners give chase, hijacking the bus, torturing, stripping, and binding the men, while terrorizing the other passengers. The scene tightens the film’s themes of vengeance and the cost of society’s cruelty.

In another surreal moment, the prisoners are ostracized by society, a cinematic echo of their earlier torment, and their retaliation against a world that deem them less than human grows more pronounced. As the bus nears a checkpoint, Oba uses Matsushima as a decoy; Matsushima is captured, but Goda’s men set up a roadblock—an enormous truck carrying Haru’s young son—aimed at forcing the bus to stop. Haru rushes toward her child, but is shot by sniper guards. Oba commands the prisoners to kill the hostages, killing the bus driver and seizing the bus’s control to bypass the roadblock.

By night, the bus is cornered by the police. Goda orders Matsushima to learn the truth about the hostages, and she lies, claiming they have been killed, prompting a police charge. The prisoners throw the three men out, and they are felled by police bullets. In the ensuing struggle, all the prisoners but Oba die; Oba survives a subsequent injury and is set to return to prison in the same vehicle as Matsushima. Goda orders the guards to finish Matsushima off, but Oba intervenes by biting a guard, buying Matsushima time to escape. In the junkyard, Oba dies, and Matsushima finally breaks free.

Goda is promoted, stepping into a city job that symbolizes the system’s capacity to normalize cruelty. Matsushima tracks him down and ends his run with a series of stabbing blows, a personal and brutal reckoning that feels both earned and devastating. The film closes on a haunting, dreamlike tableau: all the female prisoners, dressed in their striped uniforms, run free through the city as they pass a shared dagger among themselves, a collective symbol of what they have endured and what they dare to reclaim.

Q2

Why does Goda order the public rape of Matsushima?

A.

Goda orders the four guards to rape Matsushima publicly as calculated punishment for her attack and as a warning to other inmates. This is not merely sexual violence, it is a deliberate spectacle designed to dehumanize Matsushima, destroy her dignity, and terrorize the other prisoners into submission. The assault reinforces Goda's absolute power and serves as a tool of institutional control.

The film establishes Goda's promotion as tied to maintaining order, making his brutality a tool of career advancement.

Q3

Q4

Why does Oba confess to drowning her son and stabbing her unborn baby?

A.

Oba confesses her crimes in the abandoned village after discovering her husband's infidelity, a betrayal that drove her to extreme violence against her own children. This confession reveals the depth of trauma each prisoner carries and establishes Oba as someone whose crimes stem from personal devastation, not inherent evil. Her story connects to the film's themes of women destroyed by men and the sins that haunt them.

The abandoned village setting itself feels purgatorial, a place where secrets are exposed.

Q5

Why do the prisoners kill the hostages at the checkpoint?

A.

The prisoners kill the hostages, including the bus driver, because Oba orders them to eliminate any leverage the authorities might use against them. When Haru's young son is used as a human shield in the roadblock, the situation escalates tragically. Oba's command reflects the prisoners' transformation: having been dehumanized by society, they now treat human lives as expendable in their desperate flight for freedom.

The checkpoint trap mirrors earlier institutional cruelty, the system uses Haru's child as a weapon, provoking the final tragedy.

Q6

Why does Haru rush toward her son and get shot by guards?

A.

Haru rushes toward her young son when she sees him on the truck at the roadblock, disregarding the danger, because her maternal instinct overrides all survival logic. The guards specifically position the truck with her child to force the bus to stop, a cruel manipulation of her weakness. Her death while trying to reach her child underscores the film's exploration of how the prison system destroys even the most basic human bonds.

Earlier, Haru risks everything to secretly visit her son at home, demonstrating her overriding maternal devotion.

Q7

Why does Goda get promoted to a city job after the prison riots?

A.

Goda receives a city promotion despite the chaotic uprising and escape because the system rewards his effectiveness in crushing dissent. His brutal methods, including ordering sexual assault as punishment, succeed in restoring order, and the institutional machinery interprets this as success. His promotion symbolizes how cruelty is normalized and rewarded within patriarchal power structures.

The film opens with Goda on the verge of promotion, and his violent crackdowns directly serve his career advancement.

Q8

Why does Matsushima track down and kill Goda after escaping?

A.

Matsushima tracks down and murders Goda because his promotion represents the ultimate injustice, he escaped consequences for ordering her rape and torment. Her revenge is both personal catharsis and a statement against a system that normalizes cruelty. The stabbing is prolonged and deliberate, giving her the reckoning the legal system refused to provide.

God's earlier promotion sets up this final confrontation, his reward for brutality becomes his undoing.

Q9

Why does Oba use Matsushima as a decoy at the checkpoint?

A.

Oba uses Matsushima as a decoy to trick the authorities into believing she has been captured, allowing the others to attempt passage through the checkpoint. This tactical sacrifice demonstrates Oba's willingness to risk herself for the group's survival, though the plan fails when the roadblock with Haru's son is deployed. It also shows the desperate pragmatism the prisoners have developed.

The prisoners have already survived multiple near-death situations, forcing them to make impossible choices.

Q10

What is the significance of the old woman in the abandoned village?

A.

The old woman in the abandoned village serves as a surreal conduit for confronting each prisoner's sins. She wields a dagger and guides the prisoners through symbolic imagery of their crimes before dying and turning into leaves, a metaphorical purgation. She gives Matsushima a knife, symbolically passing the burden of judgment and vengeance. This sequence represents the psychological weight the women carry.

The village is empty and dreamlike, signaling a shift from realistic narrative to symbolic revelation.

Q11

What does the final scene with the dagger passing between prisoners mean?

Q12

What drives Matsushima's path from prisoner to vengeful killer?

A.

Matsushima's transformation from a wronged woman to a relentless avenger stems from systematic brutality: betrayal by the detective she loved, brutal solitary confinement, public rape ordered by Goda, and constant violence. Each assault strips away her humanity until only cold resolve remains. Her revenge is not merely personal, it represents all women crushed by a cruel patriarchal system that offers no justice.

The film establishes her initial defiance in solitary confinement, where she prepares her spoon-weapon for eventual retaliation.
