Topaz

When a Soviet official defects to the United States, he brings with him claims that Russia is using Cuba as a staging ground for nuclear missiles. CIA agent Michael Nordstrom (John Forsythe) enlists the help of French spy André Devereaux (Frédérick Stafford) to find out if the official's claims are true. Not only do the agents discover that the Soviet's suspicions are valid, but they also find out that a French spy ring known as "Topaz" is working with the Russians to uncover NATO secrets.
