At a ramshackle cartoon studio, everyone goes home except one dedicated cartoonist drawing Beans's latest adventure. After dozing off, the gorilla-like, demon-faced beast he has drawn laughs evilly and pulls the cartoonist into the drawing. It's time for revenge. He and his ilk have made cartoon villains the chumps for years; but now, thrown into a cell filled with his own villains, he'll be the chump. The cartoonist is knocked about by Battling Barney the Kangaroo, a cruel octopus, Spike the Spider, the Mad Doctor, Villain No. 999 and others. They force the poor cartoonist to draw the pit into which he'll be thrown. But Beans, trapped behind prison bars that were meant to protect him, will save the day.
