Rumen is 13, a head taller than his classmates, and overweight. He's an introvert and an outsider; no one seems to know his real name. Everyone just calls him the Pig. He can't depend on his teachers for moral support, nor can he expect unconditional love at home. Rumen lives with his grandmother; his only contact with his parents is via cell phone. In spite of this, he endures the loneliness, the insults, and occasional violence — until one day, pushed to his limits, he instinctively strikes back, with unforeseen consequences.
