Legendary jazz musician John Henry Giles is checked into the hospital and when he’s told he’s dying from ALS, he signs a DNR to avoid a slow death. House disagrees with the diagnosis and goes against everyone’s wishes when he violates the DNR to save Giles’ life. The decision lands House in court, drives Foreman to consider taking another job, and results in Giles’ paralysis worsening. But when the patient inexplicably starts getting better, the team has to figure out the mystery in reverse and find out why his condition is improving.
