The cartoon opens with assorted things being shown that make fun of small town prisons and various criminal practices. At the end of that sequence, a bloodhound is shown trying to sleep, when he is interrupted by a radio broadcast that annoys him to the point where he breaks the radio with a mallet. Porky then enters with a paper that has a picture of a wanted Nazi spy on it, the bloodhound eventually sneezes itself, and Porky, out of the town jail and it also blows the flyer onto the spy's face. The spy then tries to fool Porky into believing that he is not the spy when he comes after him. Eventually, the Nazi's plan to blow up the bridge is revealed and he activates the bomb timer, after which Porky and the bloodhound work to stop it. Porky eventually captures the bomb and when he hears its ticking throws it and runs from the bloodhound who retrieves it and this sequence continues until the Nazi spy is cornered in an area by the bomb, just when it is about to explode; it turns out to be a dud. The Nazi is blown to bits by the dud when he slams it on the ground and it ends up in heaven with him saluting Hitler.
This cartoon was apart of the Sunset Productions package of Looney Tunes shorts.
