Plot A secret strength formula for mice has been developed, and Speedy is tasked with getting it to the Mouse Factory. Unfortunately, Daffy has been sent by a rival agency to stop him. Daffy uses a variety of inventions to cut the mouse off or nab him, all of which backfire on him, or Speedy outwits him. The final plan, a mouse-seeking missile, is changed by Speedy to a duck-seeking missile; Daffy frantically returns to his base, and it blows up there. Speedy pops in the door and says to Daffy, "I want to tell you a little secret. Us good guys always win!"
