Porky Pig is eating large amounts of food to the rhythm of an exercise radio broadcast. A mouse then proceeds to sneak up and makes a sandwich out of Porky's finger. Porky then tries to drive the mouse off, but then he is suddenly startled by a radio announcement that killer Bluebeard is at large and Porky frantically bars and locks up his house. The mouse then decides to bully Porky by disguising himself as Bluebeard and threatening Porky until he offers him some food. As Porky is busy getting the mouse a drink, he is alerted by a radio newsflash that gives Bluebeard's height away as 6' 11. Porky then measures the rodent as 3 inches. Porky pursues the mouse with a meat cleaver. Then Porky pulls out the real Bluebeard by accident from under the table. While Porky is strapped to a rocket, the mouse pretends to be Bluebeard's conscience in the middle of his meal. The harassment then continues and ends with Bluebeard getting hit five times by the mouse with pies to the face in various containers. Meanwhile, Porky manages to stop the fuse on the rocket and Bluebeard builds a guillotine to kill Porky instead. Just as Porky is about to be executed by Bluebeard, the mouse decides to help Porky by tricking Bluebeard into eating some bombs, which the murderer mistakes for popovers. After consuming them, Bluebeard knows that something is wrong and takes to the medicine cabinet, mixing together every drug in it. Before he can administer the resulting concoction, however, he is exploded to his death. In a final scene, Porky happily shares a meal with the mouse. The mouse indicates his fat tummy to the audience and pats it contently.
This film is a rare example of a Warner Brothers short in which a character (apparently) dies without a comic postscript (for example, reappearing as an angel or a ghost).
