Plot

Small-town layabout Bill "Scats" Small is a whiz at figuring out the stock market, but he has no money to actually invest in it. He prefers not to do any actual work and is happier just playing his trumpet, annoying the family he rooms with. Eventually, he gets a job with a touring band, but when next he returns home, he finds himself in a hotbed of romantic and larcenous intrigue and has to use all his wiles to clean up both messes.
