Pnin is a professor of Russian at an American college who takes the wrong train to deliver a lecture in a language he cannot master. Pnin is a tireless lover who writes to his treacherous Liza: "A genius needs to keep so much in store, and thus cannot offer you the whole of himself as I do." Pnin is the focal point of subtle academic conspiracies he cannot begin to comprehend, yet he stages a faculty party to end all faculty parties forever.
