In a crumbling urban wasteland known only as 'The Zone,' where the undead known as 'It' reign supreme, a lone scavenger discovers a decrepit radio signaling human survivors. Armed only with fragmented knowledge and a salvaged weapon, the scavenger faces relentless hordes to relay the existence of 'The Zone' to the outside world and possibly orchestrate a mass rescue before the 'It' overwhelm the last vestige of hope.
