Off-track betting gambler Anica (guest star Cynthia Nixon) collapses in front of House while theyre both following horse races at the site. Confused by her symptoms and what he witnessed after she collapsed, he instructs medics to take her to Princeton Plainsboro and takes her case. After the team discovers shes been seeing a number of doctors for a variety of supposed illnesses, everyone but House thinks its Munchausens, a disease that causes people to fake symptoms for the medical attention. House butts heads over Anicas medical care with his former team member and current supervisor Dr. Foreman. Standing by the Munchausens diagnosis, Foreman sends Anica home over Houses objections. Convinced she is legitimately ill, House draws a confession out of Anica that may save her life.
