The tranquil expanse of Mizubiki's winter forest creates a serene atmosphere as the story unfolds. At the heart of this narrative is Takumi, a widowed father navigating life with his spirited eight-year-old daughter, Hana. Their daily routine reflects the calmness of their rural Japanese village, occasionally disrupted by the distant sound of gunfire from deer hunting expeditions.
During a community meeting, tension fills the air as two representatives from a glamping development company, Takahashi and Mayuzumi, present their proposal to the skeptical townspeople. The polished veneer of their public relations pitch soon crumbles under the weight of residents' genuine fears about the project’s potential impact on Mizubiki's fragile water systems. Takumi, along with his community members, voices strong concerns regarding septic tank capacity, warning that it could lead to sewage contamination affecting their well-water supply.
Initially dismissive of the villagers' worries, the representatives gradually begin to empathize as they truly listen to their plight. However, once they reestablish communication with their superior, they receive orders to sidestep the environmental concerns and instead aim to win over Takumi by lavishing him with gifts and offering him the role of caretaker for the glamping site. Back in Mizubiki, Takahashi and Mayuzumi share amusing stories of their own online dating misadventures, revealing their disillusionment with their corporate job.
As they adapt to village life, Takahashi decides to abandon his fast-paced urban existence, choosing instead to embrace local culture and seek guidance from Takumi. One day during a scenic drive, Takumi warns him with a tale about wild deer, explaining how even the most peaceful creatures can turn aggressive when threatened or cornered, a poignant reflection of the balance between humanity and nature. Yet the echo of a distant gunshot serves as a stark reminder of this delicate relationship.
As night envelops the village, a wave of panic sets in when news breaks that Hana has gone missing. The urgency of searching for her drives Takumi and the community into a frantic quest, leaving no stone unturned. Determined to find his daughter, Takumi partners with Takahashi on a perilous journey into the depths of the forest. Their resolve grows with each passing moment, and as they venture further into the dark wilderness, they eventually stumble upon an open field illuminated by moonlight, facing an unsettling truth.
In this desolate area, they discover Hana, who appears in a startling moment, standing near a deer and its wounded calf—an image that starkly underscores the harsh realities of life outside their village. As Takahashi instinctively moves to intervene, Takumi's fierce determination manifests in a sudden tackle that leaves Takahashi stunned on the ground. The shocking moment ultimately reveals Hana's lifeless body, her bloodied nose a chilling reminder of the unforeseen dangers upon them.
With grief-stricken arms, Takumi gathers his daughter and rushes into the forest, their frantic escape dissolving into the encroaching darkness. Meanwhile, Takahashi regains consciousness, struggling to rise, but the treacherous earth pulls him back down, leaving him to grapple with the relentless shadows of the night. The forest now echoes only with the distant sounds of footsteps and labored breathing, a solemn reminder of the desperate search rendered futile by the merciless hand of fate.
