Action and rude humor. The villain Balthazar Bratt, a former child star who's grown up to become obsessed with the character he played in the 80s, proves to be Gru's most formidable nemesis to date.

It follows the exploits of eleven-year-old Alexander as he experiences the most terrible and horrible day of his young life, a day that begins with gum stuck in his hair, followed by one calamity after another. But when Alexander tells his upbeat family about the misadventures of his disastrous day, he finds little sympathy and begins to wonder if bad things only happen to him.
