Donald and his nephews are the staff of a fire station. Huey, Dewey, and Louie, annoyed by Donald's snoring, ring the fire alarm. Soon, his bumbling sets the fire station itself on fire. They race off at the alarm, not realizing they are already at the destination, and the firefighting efforts go downhill from there.

Trivia, insights & behind the scenes
Jack King directed over 50 Donald Duck shorts; this was peak wartime escapism before Disney pivoted to propaganda.
The 'incompetent fireman' trope predates this by decades, but Disney perfected the formula here—directly influencing later cartoons like Pixar's 'For the Birds'.
