Don't Make A Sounds: thriller & mysterious

What do you do when you're sent to a hospital you've never heard of?

Melissa and Nancy decided to go there to work as volunteers. The hospital St Mary is located in the Lynch town, out of the city. They thought they were going to have less work to do and more time to dedicate themselves to every patient. But one night, Nancy wakes up and goes to a part inside the hospital that didn't exist, finding out just a little bit of the horrifying truth. But by the time when they figure everything out there, it'll be too late, because Melissa will remain inside a sanatorium, without being able to talk, because they might still be around her.
