Vincent Parry (Humphrey Bogart) is imprisoned for killing his wife. Irene Jensen (Lauren Bacall) who had her father falsely imprisoned for the same thing assumes that Vincent is also falsely accused and waits for her chance to help with his escape. For quite some time we only see the world through his eyes, and never see his face. This perspective has been very effective in other movies and adds to the mystery in this movie.
Who is the guy with the circus tent upholstery in his car? Will he prove to be innocent? And will the man and woman strike up a relationship? What perils lie ahead?
All right this is for all you analyzers these movies contain similar themes: The escape scene is a classic and the barrel is used again in "Wrongfully Accused" (1998). The first person prospective is used again in "It Came From Outer Space" (1953) where you see the world from an alien viewpoint. (Agnes Moorhead) The orange car is close to the red hair in "Bachelor in Paradise" (1961). The end relates to "On the Beach" (1959).
Second time through this movie, you will find your self, rooting for the good guy, want to warn him that you saw the movie before, and know what is going to happen. However, does he listen? Of course not. Nevertheless, maybe next time he will. Get out your popcorn and be aware of strangers barring chocolates.
