In a "Rip Van Winkle" type caper The IMF team tricks Rogosh into thinking that it is three years in the future, that he is in his own country, and that he is to be tried and shot for being an American Spy!

on an eight-track tape in a parked car:
Good morning, Mr. Briggs. This man is Imre Rogosh, known to us as "The Monster". His specialty is mass murder in order to create political anarchy. Here is some samples of his work: North Africa, Bombay, Rio de Janeiro. Yesterday, Rogosh was discovered to be in Los Angeles for a week. He's bought airline tickets home for tomorrow night. Considering Rogosh's history, the Secretary believes that thousands in the Los Angeles area might die unless Rogosh's plan is discovered and countered. Dan, our experts consider Rogosh unbreakable by any known means. Nevertheless, your mission, should you decide to accept, would be to break Rogosh, fast. As always should you or any member of your IM Force be caught or killed, the Secretary will disavow any knowledge of your actions. Please destroy this recording by the usual method.
