Fatty and Buster play automobile mechanics and firemen at a garage in a fire station. Mollie Malone plays the boss' daughter who is constantly pestered by a stranger named Jim (McCoy) who wishes to make her his girlfriend, though she turns him down after the flowers he brings her end up accidentally soaked in motor oil thanks to Fatty and Buster. Livid, Jim raises the alarm in the fire station to make Fatty and Buster think there is a fire and forcing them to rush across town. However, Jim accidentally starts a real fire while trying to exit the station and Fatty and Buster immediately return to put out the fire and rescue Mollie who is trapped inside. They attach the fire hose to a hydrant, but the hose has a leak, forcing Fatty to sit on it. After a streetcar runs over the hose, Fatty, Buster and several of the townspeople rescue Mollie using a life net but she bounces up into the telephone wires. Fatty and Buster eventually get Mollie down but become trapped themselves; luckily Mollie moves a car beneath them just before they fall and all three ride off together.
