October, 1939 A young boy about the age of eight is hiding beneath the streets of Berlin. He has no family, at least not anymore. He is all alone in his world with a diary and a basket of molding bread. From above, he can hear everything. He knows just about everyone in the neighbourhood...but they don't know him. A German young girl discovers him and his hiding place and they begin a forbidden friendship that escalates into a passion for one another as they get older. At night she comes into the streets to bring him bread and water. All alone, they talk about their two very different lives. As the sun emerges from behind the rooftops, she returns to her room and writes in her diary about her relentless love from him. Will they be found out? Will they be able to live like this forever? How will it turn out for the rule breakers of Berlin? The entire story is told through their diary entries.
