For Dan Crawford, the summer program for gifted students is a once-in-a-lifetime opportunity. His friends could never understand his fascination with history and science, so he is looking forward to meeting some like-minded people.

When Dan begins to explore the halls of the hospital, he unearths the chilling secrets of what happened there, and the lines between the past and the present begin to blur.
