While most everyone seems to know about the assassination of President Lincoln, this was just the last of quite a few plots to kill the man. In particular, getting Lincoln to Washington for the inauguration was problematic, as crowds were often hostile and bent on killing the man they blamed for the splitting up of the Union. In particular, in Baltimore, the President-elect needed to be spirited off the train quietly to avoid the hostile mobs. So, the premise of "The Tall Target" is very appropriate---as there was a lot of hatred and hostility towards the man during the war years.
John Kennedy (no, not THE John Kennedy but he's a guy played by Dick Powell) is a New York policeman who is frustrated, very frustrated. The inauguration of Abraham Lincoln is approaching and he insists that there is a plot to kill the man--however, his superiors don't take him seriously. So, he resigns from the force and boards a train headed to Washington. He's determined to do SOMETHING. Along the way, he meets up with several conspirators--though unfortunately no one believes him! And, when he captures the one of the conspirators, the local police want to arrest him instead! What is the man to do?! Aside from one small dumb scene (where Kennedy left his identification and gun in his coat at his seat--leading to serious complications), this is a bang-up film. While you know that Lincoln survived to serve as president, you still are on the edge of your seat--a sign that this is a very good action/adventure film. Tense, well-written and acted--this is well worth seeing.
