Tom runs after Jerry who hides behind a potato mound in a garden when he hears Spike the bulldog calling for help. Spike has been caught by a animal control officer and locked in the back of his truck, and Jerry is the only one who can help him escape from the truck before it drives away. Spike begs Jerry to get him out of the truck, and despite their Dog Trouble, Jerry shows Spike mercy and frees him by removing a piece of wood that latches the cage shut. Spike falls out of the truck just as it pulls away, and thanks Jerry by vowing to assist the mouse at any time at the sound of a whistle.
