I was gonna type up the whole thing but i found this on wikipedia i think this about sums it up-----
Michael has come to the conclusion that his girlfriend is cheating. He finds a platinum business card with the name 'Alex' seemingly confirming that she is cheating with the person whose name is on the card. As the video progresses, we learn that the girlfriend is working for a secret exclusive billionaire-boys-club escort agency. Her identity and visual appearance is changed regularly, usually between clients, and is confirmed by the platinum business cards she presents to each client as the night goes on. This reveals that the name 'Alex' on the card found by Jackson is one of her aliases and is not a secret lover. She senses that something is wrong, defies her watchers and runs back to Jackson's home to find him. She finds Jackson's assistant at the door, who refuses to let her in and reveals that Jackson has left and probably for good. The assistant then hands her a collection of her alias business cards revealing that her secret is out and that she has been exposed. Devastated, she is forced to return submissively back to her ruthless employees and continue on as a high class prostitute. The video ends with the ex-girlfriend being prepared for another client while Jackson attempts to sleep on a jet. Throughout the video, a strange ghostly face appears in Jackson's surroundings—the appearances seem to coincide with Jackson's despair.
