Mousketeer Captain Jerry sits mooning at his portrait of a gorgeous French mouse called List of Tom and Jerry characters, then writes Lilli a love letter and calls his assistant Nibbles (Tom and Jerry), telling him to deliver it. Tuffy goes out and, after briefly mocking Jerry's infatuation, looks at the letter, opens it and goes a deep shade of red after reading it. But as Tuffy is about to go out and deliver the letter, Guardsman Tom appears shouting "En garde!" ("On guard!" or "Fight!") and swipes his sword at Tuffy, scaring him back in. He pokes his sword through the door. Tuffy tries to tell Jerry about the cat (in very fast French!), but Jerry shows the little mouse his book, reminding him that "Un mousketeer est brave" ("a mouseketeer must be brave"). Tuffy then looks in the mirror and asks himself if he is a man or a mouse, but after going out and encountering Tom again he decides he is a mouse. Later, Tom is hiding in wait for Tuffy. Tuffy tries to disguise himself with a knight's helmet. He says hello to Tom, but Tom is not fooled. He immediately jumps in front of Tuffy and fights him. Jerry hears the commotion from outside. Tom then lifts off the helmet and it falls right on top of his head, knocking him down a nearby cellar window.
