When Dr. David Black takes an internship at a very old psychiatric hospital back home in Alabama, he vows two things--that he will be a better husband to his beautiful and loving wife Pria, and that he will stop cheating on her. Then his enigmatic supervisor Dr. Cassie Allen, a self-proclaimed witch with ties to the underworld, begins to draw him into her darkness. David finds it hard to resist her wicked sensuality, but even harder to resist her evil pull. As strange and violent deaths pile up left and right, David realizes that Cassie's psychotic behavior is connected to the mysterious hospital itself. There a demonic force threatens to destroy everything that David holds dear--his wife, his family, even his very sanity.
