More than seven decades after the Battle of Stalingrad, a mysterious nerve-gas created by Joseph Stalin unleashes an undead wave of terror through the streets of modern-day Bulgaria. World War II was raging across Europe when Stalin created a top-secret biochemical weapon that could decimate his enemies. Later, when the smoke cleared over Stalingrad, the powerful nerve gas was nowhere to be found. Flash forward over 70 years, and there's a strange wind blowing through the streets of Bulgaria. Corpses are climbing out of their graves, and the streets have been overrun by flesh-eating mutants. Though it's too late to contain the infection, US Special Forces Captain John McGahey (Paul Logan) and NATO Dr. Ana Bennett (Manal El-Feitury) are determined to escape the country alive. But they better be fast, because now the entire country is on Code Red, and it won't be long until the bombs start to fall.
