mental problems

Diamond grace. After finished college her mother offered her to work with her in her job at the Shady Acres Mental Hospital. Of course she couldn't reject the offer, you get paid so much! She takes the offer and works on weekends. Her job was to deliver medications door to door for the patients, but she's warned a lot about room A001. The top floor of the building, pretty scary up there also, it's just emptiness, and one long hallway that leads to a big mental door with precisely 12 locks on it, she's not aloud to deliver the medications up the that room, she has to simply hand the Medicine to large men who bring it to the room, she was always wanted to see who or what's in the room, all of her attempts to see was always failed by getting caught, everytime. One night when she was trusted to lock up from her mother because she had to finish preparing the next medications for tomorrow, Usually people would be scared all alone with floors and floors of crazy metal people. But ignoring the worries she had her one thought only on room A001. Her mother left her the key, which is also a key that can unlock any doors of the building, 'just a look.' She thought, 'just for a quick second, no harm done..' What could possibly happen?
