Bill, the janitor, has ambitions to become a secret service man, especially as his building is full of suspicious characters. A mysterious person gives him a package. He is in love with Gale, so he takes it to her. Then Milt offers to make him his deputy if he gets the package he is expecting, and Bill takes it away from Gale and gives it to Milt. Lillian takes it from his pocket, but Bill recovers it and dives down the register. In the cellar Bill throws some papers into the furnace. Gale, who has followed him, dives in after them, and he shuts the door. Lillian gets a bomb by mistake. She throws it down the register, and it falls on Gale and an anarchist who has dived after it. Bill is about to open the furnace door when the thing explodes. He and Gale are hurled through the air. At last Bill delivers the package to Milt, and it is found to contain Milt's dismissal and Bill's appointment to his place. Gale then offers to love him, but he tells her to go and get a reputation.
