Stay

This is based off the movie Stay written by David Benioff, which is the best movie ever. Hopefully I can serve the film some justice in writing it . This is sort of a writing exercise on my part, because I'm trying to finish a story and try to make the characters as real as possible. Advice would be snazzy!
Stay is about Sam Foster, a psychiatrist, and his patient Henry Letham who is a suicidal college student threatening to kill himself in three days unless Dr. Foster can stop him. In the process of trying to save Henry he finds that he has fallen into the hell that Henry has been living, and losing his grip on reality as well. Will Sam Foster save Henry before it's too late?
