Slippery Slim, the Justice of the Peace, serves a notice on Hiram Clutts, threatening to foreclose his mortgage unless Sophie marries him the next day. Hiram agrees that Sophie shall marry him as he demands. Sophie tells Mustang of this and they plan to elope that night. Mustang calls for her in his buggy, but they fail to make their escape unnoticed by Hiram. He chases them with a shotgun, but is unable to catch them before they reach Slim's office. They disguise themselves and Slim, not knowing who they are, performs the marriage ceremony. They then take off their disguises and Slim falls into a faint at seeing his disastrous mistake.
