House engages in a battle of wits and wills against the attending physician in charge of his detox program. When he starts to lose, House resorts to blackmail to gain the upper hand.

House asks Alvie to help him uncover incriminating information about Dr. Nolan that would allow him to blackmail his way out of the treatment center and convinces Lydia to loan him her car to sneak out a delusional patient in an attempt by House to undermine Dr. Nolan's course of treatment. But when devastating events ensue, House is humbled into reluctantly accepting help.

House returns home to Princeton where he continues to focus on his recovery, but surprises Cuddy with the news that he's making a big change in his life. Meanwhile, the team is unable to diagnose a loud-mouthed video game creator who posts each new symptom on the internet and opts for treatments suggested by the online community rather than by the doctors, and Foreman angles for House's job, but the pressure to solve the case creates tension in his relationship with Thirteen.

During a session with Dr. Nolan, House recounts the case of a woman who arrives at the Princeton Plainsboro emergency room with an unexplained illness and no recollection of who she is. While trying to solve the mystery of the woman's illness, House must also help her piece together her identity.

Facing a 6-month jail term, and the realization that he won't be there for Wilson at the end, House finds himself examining his entire life while contemplating a dismal future without his best friend.
