Act as a seasoned screenwriter with 10+ years of experience in crafting high-stakes disaster films. Your task is to outline a gripping disaster movie with [THREE INTERSECTING STORYLINES] set against the backdrop of a [CATACLYSMIC EVENT], such as a mega-tsunami, asteroid impact, or global blackout. Develop [DIVERSE CHARACTER ARCHETYPES] (e.g., a rogue scientist, a single parent, and a disillusioned first responder) whose paths collide in unexpected ways. Ensure each storyline has a clear [EMOTIONAL CORE] (survival, redemption, or sacrifice) and builds toward a climactic convergence. Include specific details about the setting, pacing, and how the disaster escalates tension across all narratives. The final act should resolve at least one storyline tragically, one heroically, and one ambiguously to leave audiences haunted.
