Ronald Reagan called this piece of history - largely unknown until now - “one of the most important espionage cases of the 20th century.” FAREWELL begins in 1981, after the Soviet invasion of Afghanistan.

Grigoriev begins passing Froment highly sensitive information about the Soviet spy network in the US.
