Old-fashioned gorefest about a mad scientist and a deadly mutating virus. Russian scientist Viktor (Divoff) get the pharmaceutical shaft after discovering a cancer cure. To get even he develops the rage virus, which turns the infected into flesh-eating mutants. One of his test subjects escapes, dies in the woods, and becomes dinner for vultures. The infected birds then attack any unfortunates they find, some of whom eventually turn up at Viktor's cabin. There's lots of limb-ripping, blood-gushing, and flesh-noshing with some decent special effects.
