After a gambler collapses in front of House while they're both betting on horse races, the team soon discovers she's been seeing a number of doctors for a variety of supposed illnesses. This leads everyone, but a skeptical House, to believe that it is Munchausen's which is a disease that causes people to fake symptoms for the medical attention. Of course, with Foreman as House's supervisor, it becomes more difficult for him to get things done his way.
