England, May 1941. In the North Atlantic, German U-boats are devastating the British supply convoys, pinpointing their location with uncanny accuracy. Enter Ian McLeod, a lonely, asthmatic, little boy of eleven, bullied by all the other children at school, who escapes his horrible everyday reality by living in a toy soldier fantasyland of spies and secret codes. Until one day his fantasies become reality when he discovers something that could not only save not only his Royal Navy Captain father but the entire Atlantic convoy that he commands from an "attack at noon." The clock is ticking...
