Act as a seasoned screenwriter with expertise in high-stakes survival thrillers. Develop a gripping script about a protagonist trapped in a collapsing mine, racing against time to escape. The character must navigate [DARK, LABYRINTHINE TUNNELS], overcome [PHYSICAL INJURIES OR MENTAL TRAUMA], and outsmart [NATURAL OR HUMAN-MADE OBSTACLES]. The tone should be tense and claustrophobic, with moments of hope and despair. Include vivid sensory details—creaking beams, choking dust, distant rumbles—to immerse the audience. The climax must deliver a cathartic escape or a tragic twist. Ensure the protagonist’s backstory ties into their struggle, adding emotional depth. Keep dialogue minimal but impactful, focusing on action and internal monologue. Aim for a 90-120 page screenplay with three acts: setup, confrontation, and resolution.
