The stooges' friend Jerry convinces them to buy an insurance policy on Curly and then have him act insane to collect. Moe and Larry put Curly on a leash and take him to the insurance doctor and have him act like a dog. But the plan backfires when the doctor wants to perform a brain operation on Curly.

Messrs. Hook, Line and Sinker decide to get out of the fish business and into the saloon business. But their business broker mistakenly believes they want to buy a beauty salon, and sells them a dilapidated shop in Mexico. The stooges are three fish peddlers who, looking for a new business opportunity, open a beauty salon south of the border. Their first customers are some chorus girls from a local night club. After the stooges completely ruin the girl's hair, and their manager finds out, the boys must leave on the run.
