Leo Fong is Leo Wong, a struggling private detective in San Francisco, who is hired by Troy Donahue to find the cult which has forced his daughter into a life of agricultural servitude.
That's technically the plot, but you could be forgiven for losing the thread almost immediately. Low Blow is a movie that has a tendency to wander off now and then. The main reason to watch this is to see Leo Fong repeatedly fuck up his car, kick various asses at the lowest energy level imaginable and mumble his dialogue.
...and I wouldn't have it any other way.
Cameron Mitchell, as the cult "leader" is barely awake through this entire film, and Donahue laments the disappearance of his daughter like a man reading lines from a page. Akosua Busia, as Karma, is doing the best work here as the power behind Mitchell's La-Z-Boy throne.
