Michele is 13 and lives in a quiet seaside town. Nobody would say he was popular at school nor is he a brilliant student nor is he very good at sports. But deep down, he does not care. Michele would settle for catching the attention of Stella, the girl he cannot help looking at all the time in class. But he has the feeling that she is totally unaware of his presence. But one day the monotony of normal life is shattered by an extraordinary discovery: Michele looks in the mirror and finds that he is invisible. The most incredible adventure of his life is about to begin.
