The Big Noise is retired textile manufacturer Julius Trent (Guy Kibbee). Seeking a new outlet for his entrepreneurial energies, Trent buys a half interest in a thriving dry-cleaning establishment. This gets him mixed up with a gang of protection racketeers, who promise dire consequences if Trent doesn't dance to their tune. But our hero is not so easily frightened, and with the help of his fellow merchants Trent forms a strong united front against the crooks, utilizing a clever strategy of "divide and conquer." This Warner Bros. programmer bears no relation to the later Laurel and Hardy vehicle The Big Noise.
