Cinematic horror-action short film set in a corporate office boardroom, opens with an immediate strong hook, natural realistic pacing, grounded practical-effects style, no over-acting. Boardroom with a conference table, laptops, a projector screen showing a financial presentation slide, fluorescent lights, glass walls. The manager stands at the head of the table delivering her presentation, wearing a red top, white jeans, and heels. Five employees (including two women) sit around the table facing her, attentive. One female employee wears a white top and black jeans. Natural handheld camera work, muted authentic color grading, all sound fully natural and diegetic — no music, no artificial sound design. **[0-1s]** Hard cut: close-up on the manager mid-presentation, gesturing at the screen, all five employees watching her attentively around the table. **[1-2s]** The employee in the white top and black jeans suddenly gasps sharply, gripping the table edge. **[2-3s]** Dark veins rip rapidly across her neck and face, her body convulsing violently in her chair. **[3-4s]** Her eyes turn milky white — she rises abruptly, now infected, lunging at the colleague beside her. **[4-5s]** She bites into his shoulder, he cries out, the other employees scrambling back from the table in shock. **[5-6s]** Veins spread fast across him too, convulsing hard against the table. **[6-7s]** He rises seconds later, eyes clouded white, joining her, both lunging at the next employee. **[7-8s]** Chaos erupts around the table: employees scream, chairs toppling, scrambling toward the glass doors. **[8-9s]** The manager, still standing at the head of the table, grabs a laptop, gripping it like a weapon. **[9-10s]** She swings it hard into the infected woman — a solid impact, she staggers back into the projector screen, glass cracking. **[10-11s]** The manager grabs an office chair next, swinging it into the second infected, sending him crashing into the glass wall. **[11-12s]** The last infected charges at her; she sidesteps and grabs a fire extinguisher from the corner, swinging it hard. **[12-13s]** It collapses motionless, the room falling into heavy silence. **[13-14s]** Wide shot: the boardroom wrecked — chairs overturned, papers scattered, all infected down on the floor, the manager standing alone at the head of the table, breathing hard, blood on her red top. **[14-15s]** Final shot: she lowers the extinguisher slowly, exhausted, dust settling in the fluorescent light, scanning the silent room. Cut to black. All sound fully natural and diegetic throughout — gasping, convulsing, zombie groans, screaming, impacts, heavy breathing. No music, no text overlay, no watermark. Natural handheld camera with realistic shake during the action, muted desolate color grading.
