December 5, 1957. London is once again being held hostage by a thick pea soup fog. The ever reliable Bus 11 drags itself through the horrible weather when Eddie Adams gets on. Publicly he is known as a brilliant researcher at the University of London, but unbeknownst to the rest of the world he is a Soviet spy. On the bus his boss is waiting for him: Jerry Gerard, who expects a piece of critical information. A meeting is about to take place.
