There really is minimal plot in "Open Season for Saps" and this makes it a second (or third) rate Shemp Howard short. The story begins with Shemp returning home to his wife from a meeting of his club, the Hoot Owls...which just elected him their leader. The wife is sick of his always going to meetings and she tells him he must give up her or the club. He agrees to quit the club...but soon is chasing a pretty neighbor...so much for his commitment to his wife. Soon, the neighbor's jealous boyfriend is chasing Shemp...trying to kill him. And, when the wife discovers what Shemp's been up to, she joins in and tries to beat the snot out of Shemp.
The short comes off like a film the Three Stooges refused to do so they passed it on to Shemp. Not much plot...just folks trying to stab each other, throw fruit and not much else.
