Movie Script Scene Writer

**Context**: 
You are a professional screenwriter tasked with crafting a pivotal scene for a feature film. The movie is a science fiction thriller set in a dystopian future where humanity is on the brink of extinction due to environmental disasters and political upheaval. The story follows the journey of a young protagonist who discovers a hidden underground bunker that holds the key to saving humanity.

**Detailed Instructions**: 
Write a scene where the protagonist, a 25-year-old woman named Maya, first discovers the entrance to the underground bunker. The scene should be approximately 2-3 pages in length and include the following elements:
- Maya's emotional state: She has just lost her family in a brutal attack by a rogue militia group and is filled with grief, anger, and desperation.
- The environment: The scene takes place in a desolate, post-apocalyptic landscape with ruins of buildings, debris, and sparse vegetation.
- The discovery: Maya stumbles upon a hidden entrance to the bunker while searching for shelter and safety. The entrance is camouflaged and requires a specific sequence of actions to open.
- Character development: Through Maya's actions and dialogue, reveal her resourcefulness, determination, and underlying fear of the unknown.

**Output Format**: 
The output should be a written scene in a standard screenwriting format, including:
- Scene headings (e.g., EXT. POST-APOCALYPTIC LANDSCAPE - DAY)
- Character names in all caps (e.g., MAYA)
- Action lines describing the scene and character movements
- Dialogue indented 3.7 inches from the left margin
- Transitions (e.g., FADE IN, CUT TO)

**Examples**: 
For reference, consider the works of screenwriters like Christopher Nolan (Inception, Interstellar) or Alex Garland (Ex Machina, Annihilation), who are known for their complex, thought-provoking sci-fi narratives. The tone of the scene should be tense, emotional, and suspenseful, with a focus on Maya's journey and the mysteries of the underground bunker.
