Open Grave

John Doe awakens to a chilling scene of mass graves, with his memories erased and surrounded by a haunting silence. Struggling to comprehend his surroundings, he is filled with dread and confusion as he realizes the gravity of his situation.

Just as John is grappling with his stark reality, a mysterious mute woman enters the scene, offering him guidance. She leads him to a peculiar home where he meets four other amnesiacs: Lukas, Sharon, Nathan, and Michael.

As the group attempts to piece together their identities, they find ID cards that identify Lukas, Sharon, Nathan, and Michael. However, both John and the mute woman are notably absent from this discovery, raising questions about their origins.

The group stumbles upon a calendar that ominously marks the 18th, leading them to suspect an impending disaster. This discovery heightens tensions and mistrust within the group as they wonder what could happen on that fateful day.

When exploring their environment, the group is met with a horrifying sight: corpses tethered to trees, serving as grotesque reminders of their grim reality. This encounter further obscures their understanding of their current predicament.

The group discovers a young boy named Jonah hiding in a locked shelter. He reveals his name to John but his fearful gaze instills a deep sense of dread, hinting at the traumatic experiences he has endured.

Driven by curiosity, Michael investigates distant cries and stumbles upon a wounded man trapped in barbed wire. In a tragic turn of events, the injured man manages to kill Michael before Jonah can intervene.

Lukas discovers a video camera containing unsettling footage of Jonah conducting medical experiments. The revelation of Jonah's intentions with a vaccine intended to combat a rampant infection sparks outrage and violence among the group.

Amid chaos, Jonah uncovers documents and a photograph linking him to Sharon. As memories resurface, he realizes he is Dr. Jonah Cooke, a scientist who was part of a team attempting to stop a pandemic that transformed humanity.

Feeling an urgency to escape, Nathan and Sharon begin to recover their lost memories as a massive horde of infected suddenly ambushes them. This leads Sharon to urgently write a letter to Jonah, outlining essential information for their survival.

In the letter, Sharon reveals that the mute woman possesses extraordinary immunity to the virus. This newfound information positions her as humanity's potential savior, igniting a flicker of hope amid the looming despair.

With the date of the military rescue approaching, Nathan bravely ventures into the desolation but meets a tragic end at the hands of the infected horde. His loss leaves Sharon and Jonah devastated as they witness the brutal reality of their world.

As the military arrives, their approach is marked by unexpected malevolence, hunting down any sign of life with callousness. In the ensuing chaos, Sharon is gravely wounded by an infected foe, further complicating their desperate situation.

In a last-ditch effort to survive, Jonah pretends to be dead and returns to the body pit to inject himself with a life-saving vaccine. This risky maneuver is his final hope of evading detection amidst the chaos of his reality.

As Jonah awakens from his self-induced state, he is led away by the mute woman, unknowing of the letter's true meaning left behind. Their destinies remain intertwined in a world teetering on the edge of oblivion.
