When the wimpy chess club members take on the football in-crowd and the local ruffians, hold on to your hula hoops! In this 1950s malt shop setting, supernerd Julius Caesar Abercrombie, captain of the Mighty Armadillo Chess Club, is accidentally hypnotized, and upon a particular signal, thinks he is the star quarterback of the high school football team. It's a lucky thing, too, because the real quarterback, Bobby Diamond, has promised the local ruffians that he will throw the big game if they will not hurt a young runaway girl. Meanwhile, the president of a very snobby sorority sets up a phony pledge party to embarrass the chess club girls. But the quiet Armadillos show how mighty they are both on and off the playing field. A kid inventor and a poetry-loving beatnik add even more rock-around-the-clock fun.
