Þegar hjólið hennar Iðunnar hverfur kemur bara eitt til greina – systurnar í Súluhöfða hljóta að hafa tekið það. Þá er verst að mamma og pabbi eru farin í ferðalag og barnapían afi pönk hugsar meira um lúsmý og eldgamlar hljómsveitir en tapað hjól. Iðunn og afi pönk er stórskemmtileg saga um flókna ráðgátu og öll vandræðin sem gamlir pönkarar geta þvælt sér í.
