The Perfect Sleep (2009)

In a timeless city, a man with no name returns to the violent, brutal domain of assassins he left ten years before back when they dubbed him The Mad Monk for his disregard for his own life and his intense devotion to one woman, Porphyria; a beautiful, luminescent woman; the girl he grew up with; the love of his life; the one thing he has ever wanted; the one thing he can never have.
