During World War 2, a Canadian Major suggests a commando raid against a German-occupied French port, where a large dry-dock is used to re-fit battleships. The British command is hesitant due to the high chance of failure, but the operation is eventually approved. The training is harsh, and several accidents occur, resulting in deaths and wounds. Major Jamie Wilson is dismayed when he discovers he will receive sub-standard equipment and an old mine-layer for transport to France. The plan involves a ship laden with explosives to be rammed into the dry-dock, and additional commandos would land to create a diversion.
