Charlie Foster runs an SIS network into East Berlin. When
Three of his couriers are arrested and London is ready to
let them rot, Charlie, in anger, does his own deal. He trades
his services to the East Germans and the Russians in exchange
for his people's freedom.

From his collaboration he builds up a complete picture of all
those in Europe who were Stasi and KGB informers. When the
Berlin Wall comes down Charlie Foster has something everybody
wants. SIS, the West Germans, the Americans and all the collaborators.
They are all determined to get Charlie Foster's list. Or Charlie himself.
