After chaos breaks out around the country, the U.S. government releases a mysterious chemical gas that takes the lives of millions of citizens. What was originally a plan to restore law and order throughout the country rapidly crippled the U.S. population and left the remaining citizens vulnerable in a world where survival is the only thing that matters. Along with a rapidly increasing crime rate, the effects of the chemical gas are causing dreadful mutations, and humanity faces the possibility of extinction. The Scavenger takes you on the journey of Kyle Quinn, a former U.S. Marine, as he navigates through the new world, dealing with his fear of contamination. At the commencement of the epidemic, his wife, Jacqui, warns Kyle to prepare for the worst. Unfortunately, the worst shows up at their front door as they are confronted by a small militia, planning to wreak havoc on anyone not associated with their cause. The only hope of survival is scavenging through his devastated hometown, in search of an antidote that could possibly reverse the effects of the chemical gas and restoring some order in the new world.
