In 1968 the East-West agreement is established to halt nuclear proliferation. One of the clauses, the Fourth Protocol, forbids the non-conventional delivery of a nuclear weapon to a target.MI5 officer John Preston (Michael Caine) breaks into the residence of British government official George Berenson (Anton Rodgers) on New Year's Eve and finds a number of top secret NATO files that should not have been there.
