This 1946 Bogart-Bacall film is notorious for a plot that doesn’t seem to make sense. However, after viewing it many times, I think I have most of the plot points covered below. Needless to say, major spoilers.
Carmen Sternwood is writing IOU’s to Arthur Gwynn Geiger for drugs. Geiger sends these to her father (very rich and very old General Sternwood) in an effort to collect on them. On at least one occasion, when Geiger has given her drugs, he attempts to take lewd photos of her while she is high.
Geiger’s main business is selling or renting pornography to otherwise respectable people, but this also gives him an in to blackmail them later. This information is contained in the code book that Marlowe gets from Geiger’s house.
The Sternwoods’ current chauffeur (whose name I forget, sorry, he never appears onscreen except for his running feet) is really in love with Carmen, and shoots Geiger to protect Carmen from him, while Carmen is high and being photographed. He then takes the photos and gets away in a Packard belonging to the Sternwoods, but is followed by Joe Brody (he just happens to be there too, along with Carmen and Marlowe), who catches up to him, takes the photos and kills him by sapping him and running him off the Lido pier in the Packard. Marlowe gets into the house too late to see much, except that Carmen is high and scantily dressed.
Geiger had an implied homosexual relationship with a young man named Carol Lundgren, described by a character in the movie as his “shadow.” After Marlowe leaves Geiger’s house, Carol hides Geiger’s body for some unrevealed reason, and later lays it out as if for burial on Geiger’s bed, again for an unrevealed reason. Carol is seen working with Brody to pack up the dirty books the day after Geiger is killed, but later the same night apparently decides that Brody must have killed Geiger, and himself shoots (and presumably kills) Brody.
In the meantime, about a month before, gambling house owner and racketeer Eddie Mars kills Sean Regan, paid companion of General Sternwood, because Regan was in love with Mars’ wife. To cover this, Mars makes his wife hide out in the country so it will seem that she and Regan ran off together. At the same time, he convinces Carmen’s sister, Vivian Rutledge, that Carmen killed Regan because Regan rejected Carmen’s advances and that always makes her (Carmen) mad. This puts Vivian under Eddie Mars’ thumb, and helps keep suspicion off of him for the killing of Regan.
This last paragraph is the main plot point that is only touched on in passing as Bogart and Bacall make heat in the final scenes. There are other plot points that, even when laid out here, make no sense (Carol’s behavior, for example). There are smaller questions, such as why does Marlowe use a cab to tail Brody and the books back to Brody’s apartment? Surely he went to the bookstore in his own car and could have tailed just as easily in that, since no-one was familiar with his car. Also, where was Elisha Cook’s character (Harry Jones) before Brody was killed.? He is in love with Agnes, who is with Brody in the early part of the film, but once Brody is dead, here is Harry trying to help Agnes get out of town, and giving up his life to save her.
So, did I miss any plot points here? Did I get anything wrong? I feel like I could publish a monograph on this movie, if anyone were interested enough to read it.
