The Ottoman Sultan asks the Queen of England to help him capture Jack the Ripper, who seems to be continuing his heinous murders in Istanbul. However, the detective unexpectedly dies on the way to Istanbul. His brother who is traveling with him, the schizophrenic psychiatrist Thomas Moore, is left responsible for capturing the most notorious killer of all time.

This is the extraordinary tale of a wounded soul barely managing to keep up his own mental health but who is still expected to capture and outsmart a serial killer who is almost impossible to catch, all while convincing the woman he loves not to commit what would become one of the most significant terrorist acts of the late 19th century.
