One sudden and violent incident triggers an awakening. A mind that has been shrouded for years by Alzheimer's disease becomes lucid for a few precious moments — just long enough to open the doors to a secret that has been buried for over thirty years.

For just a few more words. As he doggedly pursues the elusive and horrifying secret, deadly forces are at work determined to keep it buried forever.
