A government agent must track down and kill a terrorist before he loses his full memory from dementia.

Paul Schrader was not allowed to come out with the version he desired for "Dying of the Light". He took the studio cut and modified it with his artistic license to achieve a closer version of the vision he had. "Dark" is a more aptly named film that focuses on CIA agent Evan Lake's last mission as he slowly begins to lose his mind from dementia/Alzheimer's.
