The Atomic City (1952)

About this title: The city of the title is Los Alamos, where nuclear physicist Gene Barry lives and works. Terrorists kidnap Barry's son and demand that the physicist turn over the H-bomb formula. It's cat-and-mouse for a while, but when the FBI gets on the case, the criminals haven't got a chance. Outdated almost before its release, The Atomic City is still effective on a purely melodramatic level. There's a particularly tense climax played out along the mountain mesas surrounding Los Alamos.
