Twelve-year-old Tetsu eats, sleeps and breathes baseball. It's all he ever thinks about. But after the bombing of Pearl Harbor, Tetsu and his family are forced from their home into the Gila River Relocation Center, an internment camp, in the Arizona desert with other Japanese Americans, and baseball becomes the last thing on his mind. The camp isn't technically a prison, but it sure feels like one when there's nothing to do and no place to go. So when a man starts up a boys' baseball team, Tetsu is only too eager to play again. But with his sister suddenly falling ill, and his father taken away for questioning, Tetsu is forced to choose between his family and his love of the game.
