The boys are firemen who use horse-drawn fire trucks. A salesman named Fred Reardon tries to convince the fire chief to buy motorized trucks, which he turns down. Reardon tries to fight back by planting dynamite on a fire engine. A duck consumes some of the gun powder and lays an egg that sets the fire station on flames. The Stooges show up to put out the fire and save the day, in their usual comical way.
