An emergency broadcast warns of a zombie virus and orders citizens to shelter. Rosie brushes off her father's fear, claiming a relic charm protects her. On the street a bully taunts a woman in zombie cosplay just before real infected appear and the crowd panics. Families slam doors and flee, but Rosie spots a child and refuses to abandon them. Others shove and accuse her of risking everyone. The infected unexpectedly start dancing and do not bite Rosie, leaving her unharmed. Someone shouts, "Let her go," leaving Rosie caught between angry survivors and the dancing zombies.
