Set in the Nutty May Fair, the play follows the struggle of the nuts - including Kernel Walnut, Monkey Nut, William the Conker, Gypsy Brazil and Old Ma Coconut - against the villainous confectioner Professor Jelly Bon Bon, who is searching for nuts with which to create a new chocolate assortment. The "Chocolate Squirter's" aims are eventually foiled, thanks to the nuttiness of the Nuts and the audience's help.
