A legendary jazz musician named John Henry Giles collapses during a recording session. House and his team are told to only treat him for his pneumonia, and not his partial paralysis. John Henry files a Do Not Resuscitate (DNR) order, and chokes during a routine exam. House ignores the DNR order and ends up in court. All the doctors, including John Henry's own doctor, except for House believe that he has ALS. Cameron notices a blood clot, which is removed with surgery. John Henry recovers, and an MRI shows that he had suffered from Arteriovenous malformation, and a subsequent corrective surgery restores his ability to walk. Meanwhile, Foreman receives a lucrative job offer from John Henry's doctor, but turns it down.
