 Bugs Bunny is enjoying his morning shower under a waterfall, singing "April Showers," when the water flow gets cut off. Bugs, thinking at first beavers are responsible, he climbs up the cliff to investigate. He meets Black Jacque Shellac, a ruthless lumberjack who wants to control the water supply. Bugs tricks the French-accented Jacque into removing a tiny rock in the dam to dislodge it. Jacque builds more dams, and prepares for what he thinks is the rabbit pulling more tricks; but of course Jacque and his dams get the worst end of a real shark and a barge full of dynamite. Certain Bugs will make more attempts to destroy his dam, the villainous Jacque fires his rifle at the waterfalls but winds up wrecking the rabbit s record player. Jacque builds "the perfect dam," one made of steel, but this time, the rabbit fights back with a series of his own. Using a cannon, Jacque proceeds to destroy them all, but his final attempt to destroy Grand Cooler Dam (thinking it s Bugs ) ends with Jacque in the custody of the federal authorities.
