Ben is 12, from a divorced family, and though he's a talented chef-in-the-making, his physique leaves much to be desired. Until now, being overweight hasn’t bothered him much. But as summer ends and school resumes, he notices the boys are taller and more mature, while many girls—especially Klára—are blossoming. Ben longs for her attention, but his body isn’t helping his cause. His size makes him a target for bullies, and even the school nurse gives him a stern warning. So, Ben—a food fanatic—must go on a diet. Klára is his main motivation, but his family and his best friend Erik support him too. After many twists and turns, Ben regains his zest for life, finds love, and wins back the friendships he nearly lost.
