Russian and British submarines with nuclear missiles on board both vanish from sight without a trace. England and Russia both blame each other as James Bond tries to solve the riddle of the disappearing ships. But the KGB also has an agent on the case.

During the Cold War, the Soviet Union captures U.S. pilot Francis Gary Powers after shooting down his U-2 spy plane. Sentenced to 10 years in prison, Powers’ only hope is New York lawyer James Donovan, recruited by a CIA operative to negotiate his release. Donovan boards a plane to Berlin, hoping to win the young man’s freedom through a prisoner exchange. If all goes well, the Russians would get Rudolf Abel, the convicted spy who Donovan defended in court.

A British spy ship has sunk and on board was a hi-tech encryption device. James Bond is sent to find the device that holds British launching instructions before the enemy Soviets get to it first.
