It's Big Block of Cheese day again! Toby has a choice between an unruly mob and lunatic mapmakers, while Donna tries to help an old friend get the ear of Sam Seaborn. Sam, still smarting over the revelation of his father's long-term infidelity, reacts poorly to the plight of a suspected Cold-War era spook, especially when he learns from National Security Advisor Nancy McNally that classified intelligence confirms that Gault was a spy. Toby sets off to talk to Word Trade Organization protestors, matching wits with an acerbic cop assigned to protect him, while CJ and Josh learn that Germany's not where they think it is. Meanwhile, the President obsesses over the site of his future Presidential library, only to be foiled by his own actions as New Hampshire Governor.
