Open with foreign head of state Dibala (James Earl Jones)) driving through the rain with an advisor. Two vans corner the vehicle and a man serves Dibala with a civil subpoena for genocide and crimes against humanity. As the adviser tells Dibala they can ignore the subpoena, Dibala begins vomiting blood.

Foreman (Omar Epps) asks Chase (Jesse Spencer) and Cameron (Jennifer Morrison) if they will stay on and replace Thirteen (Olivia Wilde) and Taub (Peter Jacobson). Cameron is hesitant about treating a man like Dibala, given the potential harm he could do when he returns to his country. Since he is a guest of the U.S. government, Cuddy (Lisa Edelstein) gives them no choice in the matter. Chase can't believe Foreman fired his girlfriend. The three find House (Hugh Laurie) waiting for them in the conference room. He is back, but is still a month shy of having a license. Unsurprisingly, House finds fault with Foreman's initial course of treatment for Dibala and steers them towards dioxin poisoning. Chase shoots the breeze with Dibala while Cameron stands and stews.

House and Foreman meet with Cuddy. Her decision is initially House will be strictly a differentials consultant without patient contact. "No procedures, no patients." House thinks he can handle the second part. With House on the path back to running the department, Foreman asks Thirteen if she wants her old job back. She thinks he's trying to break up with her and turns down his offer.

A man from Dibala's country named Ruwe tries to convince Chase not to treat Dibala. He details some of the rape and torture - including his own wife - committed by Dibala's government. Ruwe says a massacre is on the horizon.

House notices Wilson (Robert Sean Leonard) is being particularly sensitive of a lousy neighbor living downstairs. The guy is a Vietnam vet//amputee who treats Wilson like crap, but Wilson is catering to him because he is on the condo board and Wilson wants a garden renovation.

Thirteen finds out Foreman pulled a few strings to get her an interview. She agrees to go to dinner. House runs into Wilson's neighbor at the mailbox. The neighbor is particularly rude about House's cane noise.

Dibala has a heart attack. House suggests Lassa Fever (LHF), perhaps contracted by a recent visit from foreign dignitaries. Dibala wants the doctors to use the blood from a woman who survived LHF to treat him. The woman is from Dibala's country and Cameron is sure she is being coerced. Ruwe dresses as an orderly and goes into Dibala's room with a gun. Chase screams out and prevents the assassination. Ruwe tells Chase he lied about having a wife who was attacked, in fact he was made to torture the woman by Dibala's soldiers. Cameron suggests next time Chase shouldn't yell out a warning. At the next differential, House uses sign language to convey his theory that Dibala is suffering from lymphoma. After thanking Chase for saving his life, Dibala explains he believes he is actually trying to prevent genocide. Dibala's son, a student in the U.S., no longer speaks to him. Dibala does admit to mistakes in his rule.

Wilson's neighbor tells him he found House rude. Based on the neighbor's mail and a web search, House thinks he wasn't really a war hero. While trying to drop off an apology, House ends up sneaking into the neighbor's apartment. There he spots a Canadian flag. House confronts the neighbor about lying about his military involvement. His "evidence" is Canada did not send troops to Vietnam. The neighbor counters Canada did send troops to enforce peace accords and that is how he lost his arm, trying to save a boy from a land mine. The result? For 36 years he has suffered chronic serious pain.

Cameron and Chase discuss the morality of letting a patient like Dibala die. The biopsy shows Dibala does not have lymphoma, but he does appear to be losing his mental faculties.

At dinner Thirteen asks Foreman if he would still fire her if given the opportunity to re-do the decision. He says yes and she gets up and leaves.

Cameron tells Dibala's chief adviser there is no way to know if Dibala is still capable of making logical decisions. House now thinks Dibala has scleroderma. Foreman goes with blastomycosis, and Chase and Cameron agree. Dibala confronts Cameron about her talks with his adviser. He thinks she is weak for not being willing to make a move herself. Chase confronts Dibala about his plans once he leaves the hospital. Dibala says, "Whatever it takes to protect my country." Cameron requests a blood test seeming to prove House is right about Dibala having scleroderma. She talks Foreman into changing his mind and treating Dibala with steroids.

Wilson's neighbor wants to press charges against House for breaking into his apartment. Wilson gets him to agree not to see legal action as long as House moves out. House knocks the neighbor out with a hypodermic to the neck and then ties him to a chair. He has the neighbor place both arms into a box with a mirror. The illusion makes it seems as though he has two arms. After getting the neighbor to squeeze and release a fist, House relieves the man's phantom pain for the first time in decades. The neighbor sobs and thanks House.

Dibala begins bleeding in his lungs. Despite heroic measures he dies. House confronts a despondent Foreman, who is unsure which diagnosis was correct -- his or House's. House suggests he go to the morgue to find out for himself. There, Foreman discovers Chase had been there earlier. He gets Chase to admit he drew blood from another corpse to trick Foreman into thinking the course of treatment should be different. Chase essentially killed Dibala. Foreman thinks Chase should answer for the action and Chase seems content to take whatever comes. We see Dibala's son visit his father's body while Foreman destroys the evidence proving Chase's guilt.

Back in the apartment, on a lighter note, Wilson tells House the neighbor is now okay with House staying and has already approved the garden upgrade.
