[1] Marcus Cutter and a bunch of mercenaries steal Attila the Hun's breastplate from a museum in Bucharest, Romania.

Meanwhile, Samantha Gaines, Professor Radu's best student, organises an exhibition in New York City.

The breastplate is presumed to lead to a legendary Sword of Mars, which makes its owner invincible.

Once Cutter gets his hands on the sword itself he kills everybody who gets in his way, including former Korean general Kul Jae Sung, who originally paid him to deliver the weapon.

Samantha has to tackle the momentarily invincible Cutter and the actually immortal beast Cerberus at the same time.
