Ancient Virus Turns Humans Into Zombies, So the Government Decides to Bomb the Entire Hospital

Summary

In a near-future climate collapse, melting polar ice releases deadly bacteria, and the world spirals into food shortages and riots. In Thailand, the government claims that isolation has kept them safe—while the powerful Versus Corporation supplies “abundant” resources. Delivery driver Sing—a former Thai boxing fighter—takes what he believes will be his last mission with his coworker Kriang, only to discover the streets are already collapsing into violence and infection.

Sing’s mission goes wrong (and right)

Sing and Kriang fight through a gang attack in Bangkok with nonstop brawler energy—Sing uses real street-fight instincts (and ring skills) to beat them back. Their delivery job pays off oddly: they open a crate of long-stored fish that the company has apparently been hoarding for years. Sing shares some with Rin, a doctor who immediately scolds him for risking his life again—especially because he’s always promising it’s the last mission.

The rich get fish—then die (and turn)

In the “nice area” of the hospital, Versus executives dine on the fresh fish while starving crowds kill each other outside. Purich (a senior official) eats it, then violently collapses—vomiting blood, convulsing, choking—until he turns into a zombie and attacks hospital staff. The infection spreads fast: as the hospital descends into chaos, police and soldiers respond with brutality, killing people indiscriminately and intensifying panic.

Restricted hospital horror + Sing’s one-man fighting skill

Sing tries to reach the hospital, dodging police blockades and witnessing bodies falling, rapid zombification, and sudden attacks. Inside, he repeatedly clears rooms and hallways using improvised weapons—fighting with kicks, punches, chairs/tables, phone cords, and even a bottle to strike zombies in the “weak spot” (their brain).

He’s also guided by Buddy, a kid who gets separated and nearly eaten—Sing saves him multiple times, including stabbing through a zombie’s eye and rescuing him during relentless horde surges.

Rin fights her way to the upper floors

Rin hides in the restricted ward as the director turns monstrous, then flees when the lights cut out. She tries to reach security controls, but zombies keep blocking her. Eventually, she gets to where she needs to be—while the hospital massacre continues floor by floor. She also discovers there are no truly safe places, and that every moment spent searching could mean death.

The military decides the hospital must be bombed

Once the infection becomes undeniable, military leadership concludes the only way to save the city is to blow up the hospital before it spreads further. Soldiers infiltrate to set explosives while heroes scramble toward key people: Rin, Buddy’s family, and Versus executives.

Big emotional arcs: losses, reunions, and betrayal-by-infection

• Buddy’s mother Mink appears and hugs him—only to be bitten later and become a zombie, leaving Buddy devastated.
• Sing and Rin find a brief, intimate emotional anchor amid slaughter: a ring/gift moment and a promise to return home after everything ends.
• Meanwhile, Vasu (Versus head) stays focused on saving his wife—even as others plan evacuation and detonations. He refuses to leave until a doctor is secured, prioritizing love over survival.

Final rescue attempt + explosion countdown

A helicopter rescue begins, but the timeline collapses:

• The team escapes with Vasu and his wife—yet Rin is separated and must fight her own way through infected rooms.
• Zombies escalate into fish-like mutant forms (the “virus” is activated by water), making the horde far more dangerous and resilient.
• Rin and Buddy reach safety moments before being forced onto the helicopter—while Sing is stuck fighting on the ground as the building gets surrounded.

Climax: Sing holds the line as the bomb destroys everything

Sing fights through overwhelming numbers as bombs approach detonation. The hospital is ultimately destroyed—zombies scatter, mutate, and still attack, but the explosion wipes out the building and most threats inside.

Aftermath twist: Sing survives

Later, it’s revealed Sing survived by hiding in a storage tank—he still has to kill at least one more zombie to emerge. Rin returns home with Buddy, while the final note underscores that survival came at a terrifying cost.

Jokes / tone notes

The tone isn’t comedic overall—more dark and frantic. The lighter moments include:

• Sing’s fighting prowess feeling almost invincible at times.
• Small bursts of childlike reactions from Buddy (panic, yelling, brief humor when zombies fall/fail).
