A murdered police officer is brought back to life by a cold-hearted scientist to serve as "The Demolitionist," the ultimate crime-fighting weapon in a city overrun by criminals and internal corruption.

Clay Lomax is a tough-as-nails ex-felon out to avenge an injustice in the rugged 1890s Frontier Territory. He finds himself the guardian of a beguiling six-year-old girl named Decky Ortega, a homeless urchin consigned to his care after the death of her mother, while trying to evade a trio of sadistic killers hot on his trail, killers sent by the double-crossing ex-partner Lomax has sworn to find.
