December 1924, Karl Denke fails to smite Vincenz Olivier with a pickaxe. He would have been his 31st victim. The film thus reconstructs the mind, motivation, and psyche of its main character in intense dialog between him and the inspector.
As a child, Evie lost herself in the myths and legends of the sea while her family collapsed around her. A childhood tragedy and an estrangement from her loved ones means Evie must find her way in the world on her own....now the demons of her past have come to reclaim her.
