David manages to subdue an alien and takes him to a doctor. The x-rays reveal that internally he's not human. This is proof that David can take to a project that investigates the possibility of extraterrestrial contact. He offers the x-rays to the project director, Dr Crowell, but the wife of the doctor who took them recants, claiming the x-rays David offered are fakes. It's clear someone's pressured her, and that someone close to the project, Crowell's daughter, is acting strangely suspicious.
