A psychiatrist treating the president becomes a pawn in international espionage.

Unknown to successful New York psychiatrist Dr. Sidney Schaefer, one of his patients, CEA (Central Enquiries Agency) agent Don Masters, has been evaluating him for the important task of becoming the President's analyst. After being sworn to secrecy, Schaefer and his newfound girl friend, Nan, move to Washington. Here he meets CEA head Ethan Allen Cocket and FBR (Federal Board of Regulations) chief Henry Lux, who are suspicious of each other. Though a great help to the President, Schaefer, unable to speak with anyone, soon acquires the President's tensions, constantly feels that he is being followed, and even becomes wary of Nan. Seeking relief, Schaefer mingles with a White House tour group and leaves Washington for New Jersey with the Quantrills, a typical gun-carrying, karate-practicing, eavesdropping American family, who boast of being liberals and are cautious of their rightwing neighbors. Schaefer, now being pursued by secret agents of other nationalities as well, escapes with a group of nomadic hippies. Kidnaped by Canadian Secret Service agents disguised as a Liverpool rock group, they are additionally abducted by Russian spy Kropotkin. Schaefer convinces Kropotkin that he needs an analyst, and they set out together for Washington. En route, Schaefer is kidnaped by the Telephone Company, which, angered over constant complaints about its inefficiency, plans to take over the country and use Schaefer to brainwash the President. Masters and Kropotkin, old friends from previous clandestine assignments, join forces, rescue Schaefer, and destroy the Telephone Company's headquarters. Returning to Washington, Schaefer resumes his job and marries Nan, who has been cleared on a security level equal to his own. The couple, accompanied by Masters and Kropotkin, enjoy Christmas evening together, unaware they are being watched by Telephone Company automatons.
