When a renegade World War II scientist (Christopher Heyerdahl) invents a green goo capable of transforming the dead into an army of monsters, America provides the antidote -- a monster-smashing machine known as Matthew Blackheart (Rob Bogue). Born from the reanimated remains of fallen U.S. war heroes, Blackheart uses his superhuman strength -- and patriotic fervor -- to bring down the enemy's undead soldiers.
