Robin Westlin, a celebrity financial guru who gives questionable business seminars, comes to Dr. Sloan's home with a medical emergency. Despite Mark's efforts, Robin dies, but his body is gone when the police arrive. Because Mark had been on drugs from some dental work, Steve and the police assume that Mark had been hallucinating. After they leave, Mark finds Robin's personal diary. Armed with the information learned in the diary, Mark attempts to contact those close to Robin, but no one will admit that Robin is dead; they claim that Robin is busy on some important business opportunity. Jack and Amanda attempt to get information from Robin's wife and his business partner. Amanda manages to get tickets to Robin's seminar, where the team intends to confront Robin's absence once and for all. At the seminar, Robin is introduced and shown on a projection screen, supposedly live. Mark has to confront Robin's partner and expose the seminar as a fraud. Then he must determine which of the three close associates (wife, partner, or secretary/lover) killed Robin.
