In the city of Haven, a quiet war has been raging for years. Every night, when the sun sets and the streetlights flicker on, monsters crawl out of the shadows and begin to terrorize the citizens. But there's a secret organization that operates in the shadows, hunting down these creatures and eliminating them before they can harm anyone. No one knows who these hunters are, or where they come from. But they are the only thing standing between the people of Haven and complete destruction. As the attacks become more frequent and the monsters become more powerful, the secret organization must work harder than ever to protect the city and keep their existence hidden. But one day, a young woman named Elena stumbles upon the secret organization's headquarters. Shocked and frightened, she watches in amazement as they prepare to go out on a mission to eliminate a particularly dangerous monster. Intrigued, she decides to follow them and finds herself drawn into a world she never knew existed. As Elena becomes more involved with the organization, she discovers the truth about the monsters and the war that has been raging in Haven for years. But as she becomes more deeply involved, she also discovers that the organization is facing a threat more dangerous than any monster they have ever encountered. Will she be able to help them save Haven from this new threat, or will the city fall to the monsters once and for all?
