The mysterious Lady in Black claiming to be the last love of the first screen sex symbol Rudolph Valentino, dies in her Hollywood apartment. The only contact the detective finds is the business card of the young filmmaker Paul Harts. While answering the investigator's questions, Paul brings us half a year earlier to the Hollywood Forever cemetery when he first met Lady in Black and convinced her to reveal her secret on camera. The story of the old lady takes us back in the past even further, to 1926, when she was a young nurse in NYC and met Rudolph Valentino on the hospital death bed.
