Mrs. Bœuf (the wife of an employee) says that her husband is unwell and that she was chased all the way to the office by a rhinoceros. Botard scoffs at the so-called "rhinoceritis" movement and says that the local people are too intelligent to be swayed by empty rhetoric. A rhinoceros arrives and destroys the staircase that leads out of the office, trapping all the workers inside. Mrs. Bœuf recognizes the rhinoceros as her husband, transformed. Despite a warning, she joins him by jumping down the stairwell onto her husbands back. Daisy has called the firemen. The office workers escape through a window.
