Shirley, trying to dodge a bum who keeps bugging her during her lunch break at Bardwell's, notices a man nearby reading Black Beauty. She can't help but strike up conversation with the tall, dark, and handsome lug; unfortunately, she doesn't realize he's part of a gang robbing the bank next door. When the cops catch the crooks, Shirley is accused of being their accomplice and handcuffed to "Louis Armstrong" (no relation). The hoodlum makes a break for it and escapes - with Shirley still attached to him! Will she defy the odds?! Meanwhile, Laverne has a lively snooze on a park bench and Frank attempts to intervene in the crisis.
