Katya, a Russian woman, sends a manuscript to British publisher Barley. Before it gets to Barley, it ends up in British intelligence. They read it and discover that it’s from Dante, a Russian scientist who is revealing that the Russians are really far behind in the arms race. British spy Ned contacts Barley and asks him to go to Russia and contact Katya. Ned wants to find out if Dante is for real. Barley meets Katya, and she arranges a meeting with Dante, who gives Barley another notebook. Ned brings in Russell, from the CIA, and they grill Barley and ask him to make another trip to Moscow and ask Dante some more questions.

By this time, Barley is in love with Katya. When he finds out that Dante has been caught by the Russians, he fears for Katya’s life. He makes a deal with Moscow — he will give them the CIA’s list of questions in exchange for Katya’s life. And that’s it. Everything goes according to plan. Moscow gets the questions and Katya joins Barley in Spain. For some reason, the CIA decide the information from Dante shouldn’t be revealed and the arms race continues.

Connery and Pfeiffer’s characters were likeable, but nothing really happened. The movie was boring, with little suspense or danger.
