Plot

Dressed as the demigod Siegfried, Elmer Fudd sings "Be vewy qwiet, I'm hunting wabbits" in recitative, before he finds rabbit tracks and arrives at Bugs Bunny's hole. Elmer jams his spear into Bugs' hole while singing "Kill the wabbit! Kill the wabbit! Kill the wabbit!" to the tune of Ride of the Valkyries. Bugs sticks his head out of another rabbit hole and taunts Elmer about his spear and magic helmet. This prompts a display of Elmer-as-Siegfried's "mighty powers", which scares Bugs. Bugs flees and the chase begins.
