The plot of this cartoon involves Mexican Revolutionary mice. Numerous attempts to deliver a message to General Gracias fail when every messenger is caught and eaten by Sylvester. Desperate, Speedy is used to deliver the message. After overcoming several of Sylvester's attempts to thwart him, Speedy traps Sylvester and delivers the important message to the general—only for it to turn out to be "Happy Birthday" from the other general. Disgusted because he had gone through all the trouble he had with Sylvester for such a relatively trivial message, Speedy then asks the cat, "Hey, Senor gato, Are you thinking what I'm thinking?" Sylvester replies back, "I'm thinking." then Speedy sets the cat free, on the condition he eat the generals (as retribution for the rebels they allowed him to eat).
