Ask AI: Write an apocalyptic horror film with vampires, rather than zombies, as the movie's main antagonists.

Title: "Veil of Darkness" 1. Setup: The film opens in a world showing signs of environmental collapse and social disintegration. A small isolated town in the inexplicably perennial twilight of the Alaskan wilderness serves as our primary setting. 2. Main Characters: Jackson, an ex-soldier turned survivalist, is haunted by past war-wraiths. He lives with his teenage daughter, Eloise, a rebelliously curious and intelligent kid with a decent knowledge of solar engineering, passed down from her deceased mother. 3. Inciting Incident: After a radio reveal of the outside world plunging into darkness, the town experiences disruptive electrical failures, suspicious weather patterns, and encounters with unknown, violent "creatures". Eloise stumbles upon one such creature - a vampire, revealing the real threat to humanity: a vampire apocalypse. 4. Act 1 Development: Jackson, Eloise and a local nurse, Abigail, form a reluctant alliance to cope with the grim reality. They fortify their houses, familiarize themselves with vampire characteristics, and devise strategies based on survival instincts. 5. Midpoint: When a fierce vampire leader, Erebos, takes over the community radio station, he communicates their intent to overtake humanity and establishes an oppressive reign of terror. Some of the town's folks start vanishing or, worse, turning into vampires themselves, revealing an unsettling betrayal by one of their own. 6. Act Two Development: Jackson, Eloise and Abigail navigate through a network of underground caverns to reach the radio station. They meet other survivors along the way, facing betrayals, losses, and hard choices. They study vampire weaknesses, mostly exploiting their sensitivity to UV light. Eloise's solar powered gadgets prove useful. 7. Climax: Reaching the station, they fight a horde of vampires led by Erebos himself. Fighting valiantly, Jackson sacrifices himself, letting Eloise and Abigail escape. Eloise, in grief and rage, uses her mother's solar-powered invention – a concentrated UV ray emitter, killing the vampire leader. 8. Resolution: Having broadcasted a message to warn others and revealed killing vampires with UV lights, Eloise and Abigail now lead their town in these dark times. The film ends on a bitter-sweet note with an uncertain but resilient future, promising future battles against the vampire apocalypse. Remember, in every good horror film it's important to build suspense, not just through visuals, but also through strong dialogue and character development. Maintaining a consistent mood and atmosphere throughout the film will also help create the tension necessary for an effective horror movie.
