Roscoe and Buster operate a combination garage and fire station. In the first half they destroy a car left for them to clean. In the second half they go off on a false alarm and return to find their own building on fire.
Buster manages the store while Roscoe delivers the mail, taking time out for hide-and-seek with Molly. The constable, also interested in Molly, steals $300 while being observed by Buster.
