So... Uh... What was this movie about?

I don't think there was supposed to be an actual plot, so much as a character study about men on the run. So it's just a series of vignettes about criminals doing criminal things. Which is why the film is so disjointed.

It's about being caught in the machinery of the modern world.

You got the wrong flick. Mine is about the second coming.

Let it be unsaid: insignificance is the locus of true increpation.

Only saw the MST3k version, but I'd say it was about a guy that escaped prison, who tags along with two other former convicts, who try to scam the government out of an up-front $1000 payment for joining some kind of army unit that intends to overthrow Castro. But the money was a lie, so they get stuck actually invading Cuba. They get captured, but escape just before they're about to be executed. It was hard to tell to me when they actually escaped Cuba and got back to the US, but eventually they did and then they went to the home of one of the guys that was left behind, wanting to exploit a mine on his property. Then the police catch up to them and there's a shoot out. Then the guy they left behind returns. Fin.

People are placing too much thought into the plot of the movie. It's about a guy who loves coffee and hurting things while eating and drinking and with small aircraft.

I think the murdering and an implied doing of something with the Blind Girl (which was cut to make the MST3K family friendly) and drinking and and eating and stealing was just an autobiography of Coleman Francis. This is how he saw life. As a disjointed booze binge fest that stumbles from minutes of sobriety to minutes of sobriety.
