Big Jim McLain, U.S. House Un-American Activities Committee investigators Jim McLain and Mal Baxter attempt to break up a ring of Communist Party troublemakers in Hawaii (ignoring somewhat, as do their superiors in the Congress, that membership in the Communist Party was, at the time, legal in the U.S.)
Big Jim McLain, Early in the film Wayne and Arness take the US Navy “picket boat” out to Battleship Row and the superstructure of the USS Arizona, long before the familiar white memorial was built. This little side trip provides a continuity. The 50’s fear of Communism was seen, in that era, as being informed by the experience of the attack at Pearl Harbor 11 years before. Folks then knew from bitter, bloody experience, that evil in the world existed, and they were trying to thwart the new evil. It may appear ham-handed to us today, but, in the context of the times, finding the enemy through investigative techniques probably appeared preferable to another sneak attack. Having read the above comments, I also appreciate the way the writers heaped praise on the local, Hawaiian, police.
