If the Fourth Protocol is ever breached, there would be no warning, just a nuclear explosion from a bed sitter...The unthinkable has just begun.

July 1, 1968. America, Britain and Russia sign a treaty to halt the spread of nuclear weapons. They add four extra clauses. The most secret and dangerous of them all: The Fourth Protocol.

The Chairman of the KGB hatches a plan to breach the final clause, and destroy NATO. Agents, Major Petrofsky (Pierce Brosnan) and John Preston (Oscar winner Michael Caine) must race against an unknown deadline to stop him from accomplishing his devastating mission.

An absorbing intelligent and suspense filled thriller, based on the novel by Frederick Forsyth (The Day of the Jackal).
