In the film The Bridge of Spies, James Donovan is a lawyer in New York who is aware of the Cold War, like the American people, but has never thought that he could be involved in it, As we will see on the tape.
One fine day, the CIA contacts James. He does not know what they might want from a simple lawyer like him, but he finds out soon enough, as they ask him for something very delicate that only a good lawyer like he can carry out.
It is negotiations with the Soviet Union, in order to free an American military pilot who have captured the Russians, pilot who of course should not be there when they captured him.
The negotiations will not be simple, because the tension between the two countries is maximum at that time, so the lawyer will have to do his best to get the pilot home.
