Hidden

An unknown, deadly outbreak devastates the United States. Ray, Claire, and their daughter Zoe seek refuge in an abandoned fallout shelter as military bombings escalate. Inside, they establish basic rules to survive the claustrophobic conditions.

With dwindling resources, the family imposes strict rules to stay calm, keep quiet, and avoid drawing attention. They practice daily routines to create a sense of normalcy in a fragile world. The shelter becomes their only hope of safety.

During dinner, they discover a rat has been consuming their remaining rations. The family must decide how to respond while facing starvation and fear. They set out to locate and kill the rat to protect what little food remains.

The trio finds a small air duct and Ray reassures Zoe that the Breathers wouldn’t fit through it. This belief reinforces their sense of security and the plan to stay hidden. The discovery hints at a potential escape if needed.

Zoe wakes from a nightmare about the Breathers, underscoring the constant fear in confinement. The family tries to rationalize the danger, but the dream foreshadows looming threat. The moment deepens the emotional strain of their shelter life.

Claire accidentally burns a wooden table while killing the rat, and the resulting smoke drifts up the air duct. The smoke and ash visibly cover the shelter hatch, making their hiding place easy to detect. Realizing their risk, they prepare to surface to cover the shelter.

Using a homemade periscope, Zoe spots a humanoid figure in the distance on the surface. The family retreats back to safety as the threat lingers nearby. They decide to keep quiet and wait for the danger to pass.

Disregarding the rule to stay quiet, Zoe climbs through the barricade to warn her parents of the Breather's presence. The Breather begins to break in, and the family scrambles to stay hidden. They narrowly avoid detection for the moment.

In a flashback, Ray, Claire, and Zoe drive along a highway trying to flee Kingsville, only to be stopped by the CDC. Signs announce a strict quarantine, underscoring a world collapsing under containment. The moment contrasts with their current desperation inside the shelter.

A bomb blast punctuates the early outbreak, and the family rushes to an abandoned shelter as jets destroy their town. They realize the virus is airborne and that they may already be infected. This knowledge raises the stakes for every decision they make.

More Breathers arrive and force their way through the shelter hatch. Claire and Zoe retreat into the air duct, but Ray is captured and disappears amid a spray of blood. The encounter pushes the family toward the dangerous world beyond their shelter.

Soldiers test Claire and Zoe's blood and prepare to execute them. Ray suddenly appears, killing one soldier and displaying extraordinary strength before he is shot and falls. The family is left in a precarious, violent stand-off with the outside world.

Claire undergoes a transformation akin to Ray, attacking soldiers with feral intensity and killing several. Before the last soldier can kill Claire, a transformed Zoe exposes him to air, infecting him. Zoe's rage tests the limits of their resolve, but Claire urges calm to maintain order.

Claire and Zoe manage to slip free and flee toward a sewer system beneath the town. They meet Joey, Zoe's neighbor, who has survived and leads them to others like them in the underground tunnels. The group begins to reconcile their uncertain new reality.

Zoe notes that they have survived to day 302, suggesting miracles rather than a schedule. Claire looks up toward a sunlit window with bloodshot eyes, signaling infection’s toll and the uncertain fate ahead. They join the other infected survivors in the sewer, facing a long, uncertain future.
