Former Beirut Hostage John Mccarthy has never thanked Giandomenico Picco, the United Nations negotiator who arranged his release.
In this documentary John at last travels to meet him and explores the development of the role of the crisis negotiator.
The journey John Mccarthy makes is a deeply personal one.
He is intensely grateful for the role Picco took in arranging his release - at no small risk to himself - and John's journey to New York provides a compelling holding form for his wider purpose.
John is fascinated by the skills and dedication of men such as Picco, and he explores how the techniques used in negotiation have changed and developed.
With the help of archive and interviews, John contemplates the development of the role of the negotiator.
Beginning with the emergence of negotiation as a psychological study in early 70s America, he considers negotiation tactics being used in international crises and domestic incidents - can the same tactics be employed in both arenas?
The programme culminates in John's meeting with Picco.
He will endeavour, in the light of his investigations into the role of the negotiator, to answer some of his closer unanswered questions regarding the back room story that led to his own personal freedom.
