The Janitor arrives, turns his things over to the Jap valet, puts on overalls and jumper and gets to work. The President and daughter arrive, the President bawls the Janitor out for not keeping things dusted. The Janitor falls for the girl, but she won't have him until he gets fruit and flowers (from a customer's hat). John J. Villian arrives, demands his money or the banker's daughter. The banker gives him the money, and Villian leaves, but vows to return. The girl and Janitor become quite friendly. That night the girl returns to the bank for a forgotten powder puff. Villian and his confederates also return to rob the bank. The girl hurries to the vault room to hide. The Janitor hides in the vault and the girl tries to open it, but part of her dress becomes caught in the door. Crooks attack the vault. The girl gets away, calls the police and returns to the bank. The President has in the meantime been caught by the crooks, and he and the girl are both held as prisoners. The Janitor gets out of the vault, finds a keg of powder with a burning fuse, lights a cigarette from the fuse and sits thinking. Villian tries to get away and the powder explodes. The Janitor and Villian are blown through the roof and fall upon the rest of the crooks. The Janitor captures them. The cops arrive and remove their prisoners. Then the Janitor awakens to find himself being beaten by the President and is thrown out of his private office.
