The Perfect Sleep (movie, 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.
