The story of a mature professor who, on the surface, is a seemingly lucid man who has it all - looks, money, and a stable job; yet, underneath, lies a demon of sinister proportions that he has been harbouring for far too long now. When a young student befriends him, she brings a light to his life that had been lost some time ago, while, at the same time, shedding a light on his darkest secret - a secret of dangerous depths - a secret that will threaten to change both of their lives forever.
