When an old friend and former patient of Wilson's exhibits paralysis in his right arm, Wilson puts himself on the case. House wagers Wilson that the patient's symptoms are attributed to new cancer cells. Wilson accepts even though he is reluctant to believe the cancer has returned. With the help of the team, Wilson works to diagnose the patient more optimistic results, but when things take a turn for the worse, Wilson must address his inability to separate patient from friend. Meanwhile, Cuddy seeks advice in her search for real estate.
As an infectious disease specialist, Dr. Gregory House is a brilliant diagnostician who loves the challenges of the medical puzzles he must solve in order to save lives. House solves the inexplicable cases that other doctors cannot understand.
House isn't alone in this quest. His team includes neurologist Dr. Eric Foreman, a neurologist with a troubled youth and a desire to avoid becoming as abrasive as House; immunologist Dr. Allison Cameron - who sometimes cares too much and has conflicting feelings about House; and Dr. Robert Chase, a specialist in intensive care who has lived a very privileged life. House's good (and possibly only) friend Dr. James Wilson is an oncology specialist, who has to help and stand up for House on a regular basis, while trying to get him to face a few harsh truths.
House must also deal with his boss, Lisa Cuddy who, while often opposing House's unconventional methods, must admit that he is the best doctor on her staff. When a patient's life hangs in the balance, House will do anything, including breaking the law, taking risks other doctors would not take, and sometimes even going as far as actually interacting with a patient. House's methods may be controversial but his results speak for themselves.
Inconsistencies with his team forced House to hire a new batch of doctors. This year House used an elimination process and the end resulted in hiring, Dr. Lawrence Kutner, Dr. Remy Hadley, and Dr. Christopher Taub. Although his old team no longer takes orders from House they're still around to throw in their professional knowledge when need is dire. Together they will continue to solve cases most doctors can't.
