Saturday, the second day of July, in the year of our Lord, 1644, will be long remembered by those committed to ending the reign of Charles the First, after the tyrant king's forces were crushed on the bloody killing fields of Marston Moor. The calamitous defeat forced the increasingly desperate Royalists to intensify their attempts to bring about the immediate demise of their Parliamentarian enemies. This includes devising an audacious plan to assassinate the man they believe is key to the war's outcome. With the plotters ready to strike, Francis Hacker, one of Parliament's most loyal soldiers, becomes aware of the conspiracy. With little time to act, he does everything in his power to frustrate their murderous scheme. Alas, things start to unravel when brave Hacker finds himself pitted against his nemesis, a ruthless and cunning mercenary who will resort to anything to achieve a 'kill'.
