The bloody siege of Vraks has entered it's seventeenth year. The Death Korps count more than ten million dead among their ranks, and still, they continue to feed bodies to the meet grinder. As the war draws to a close, the inexperienced forces of the Carthaggan Guard's Fifth Army Group make planetfall, and join the fray, hoping to earn a place in the hymnals that will one day be written about this holiest of crusades. On a routine patrol, Matilda, a Leman Russ tank, carrying a sacred and powerful Vanquisher cannon has gone missing. The Benediction, a second Leman Russ, piloted by Captain Kunnar and his crew of seasoned veterans take on a new member, the inexperienced young soldier Soloman, and are tasked to find and recover the lost relic before the forces of Chaos can claim it.
