Minnie Penelope Peck, the village scamp of Yaptank, accompanies her father to the bank to demand the nine dollars owed him for his work as a night watchman. When the bank president refuses to pay Peck, Minnie posts a sign which states that the bank is insolvent, whereupon all of the depositors immediately demand their money. The fire department is called in to quell the mob, but things get worse when Minnie accidentally turns on the fire hose. Minnie is saved from reform school by a new woman in town, Hortense Martinot, who hires the tomboy to model clothing in her shop. After falling in love with Dick, a jewelry store proprietor, Minnie discovers that Hortense, in league with two gentlemen from the city, is planning to rob the bank. With the help of Dick, who is actually a detective, Minnie captures the crooks and then accepts a wedding ring from her jewelry salesman.
