Daffy Duck, who has mice living in his house, decides on a way to dispose of them; to send them across the seas for starving cats over there to feast on. He pretends to be helpful to the mice, however, the mice are on to him and enlist the help of Speedy Gonzales. He knows of the plan and foils the plan by tricking him into having the wrong box into a box of fireworks that injure Daffy. At the end with the mice on an opposite cliff than Daffy Duck, Daffy tries to catapult himself across. Unfortunately, he is flattened and Speedy suggests they send HIM over the seas.
