During the Cold War, the Defense Department's War Games team smuggles 48 nuclear bomb parts into the USA to test the nation's readiness for a subversive attack but an unexplained 49th bomb part mysteriously shows up.
Nowadays, it's easy for folks to make fun of the Cold War era--and in particular the paranoid 1950s. However, given the proliferation of atomic weapons and a vow from Stalin to destroy the West, it's understandable why so many films of the time were about Communist plots or giant mutant creatures created through atomic fission. So when I see "The 49th Man", I see its plot as a definite product of these scary times--a time when it seemed very possible that the human race would wipe itself out sooner or later. Because of this, the film is a lot more tense than most films--even if the plot is a little far-fetched.
The film begins with a scary discovery--a portion of an atomic bomb is found amidst car wreckage! And, scientists examining it have determined that the weapon has been broken down into dozens are pieces--and each can be easily transported by an enemy agent (i.e., a Commie!). So, it's up to John Ireland (a great Noir actor) to track down the agents and get to the bottom of this plot against America.
Taut action and good acting carry the day here. While this is not a fancy big-budget film, it is entertaining and a great window into a very tense era.
