It's hard to see that your youth has escaped you. It happens to us all. The sad personage of Christopher Cross is very touching. He has seen his life pass with a nice gold watch all he has to show for it. His wife is ugly and mean spirited, his work is dull. He is quite a good painter but hasn't time to do anything about it. Them "she" comes into the picture. All those charms, sexy, vulnerable, and evil, with a connection to Dan Duryea (what a cad) to boot. When the Robinson Character comes to her rescue, it's Johnny (Duryea) who is slapping her around. She is perceptive enough to believe that the well dressed older man must have money, and, if she plays her cards right, she can squeeze him for money. He falls, hook, line, and sinker, and really believes she cares about him. Not only is she an opportunist, she even uses his art as her own to get more money. Because he is moonstruck, he lets her go on and on. There is a subplot concerning his wife's first husband and some other things, but he slowly descends the path to destruction. Everyone watching the movie knows that the poor sap is going to get his at some point. The way it happens is a bit of a stretch. Chris should really feel very little guilt; he is victimized all long the way. But in film noir, the dark elements demand their pound of flesh. He is paid for his foolishness and trust.
