James, Lord of Douglas, known to his foes as the Black Douglas, leads a flank of the Scottish army in crushing a vast invading English force at the waters of the Bannockburn. Fresh from battle, James revels in honors heaped on him by the Scots and in the hatred of the enemy. When King Robert the Bruce orders him to push their advantage and force the English to the peace table, they both know the only way James can do so is by fire and the sword — the only language King Edward of England understands.
