0–1s: She sits on a couch in a large suburban living room at night, phone in hand, warm lamp against dark windows. 1–1.8s: Phone lights up with an unknown/no-caller-ID number. She mutters, “Weird, no caller ID,” and answers. 1.8–2.8s: “Hello? Who’s this?” Distorted voice: “Have you checked on the kids?” 2.8–3.6s: “Is this a joke?” Silence, then disconnect. 3.6–4.6s: She rises: “Just gonna check real quick,” staring toward the dark staircase. 4.6–5.8s: Static wide hallway shot; dim nightlight.

Not now.” 8.6–9.6s: Same unknown number. “This isn’t funny anymore. Who is this?” 9.6–10.6s: Voice: “Have you checked on the kids?” Her irritation turns to unease. 10.6–11.6s: “I just checked, they’re fine,” gripping phone tighter. 11.6–12.6s: Voice: “Check again. And look behind you.” She freezes and slowly turns. 12.6–13.4s: Empty hallway. “There’s nothing there.” 13.4–14.4s: Voice: “I’m not talking about the hallway. I’m already inside.” Call dies. 14.4–15.4s: Close-up: realization and terror on her face, phone trembling. 15.4–16.2s: “Okay, call 911,” fumbling to dial. 16.2–17s: Phone: “No Signal.” Panic. 17–17.8s: Floorboard creaks from a slightly open closet at hallway’s end. She freezes. 17.8–18.6s: She backs toward the children’s room: “Please, please…” 18.6–19.4s: Closet door slowly creaks farther open.

Absolute silence. 28–30s: Hold on her terrified face pressed against the door. She whispers, “…Hello?” End on unresolved dread.
