Pahan enne

Doctor Robert Verne (Robert Foxworth) and his wife (Talia Shire) travel to Maine to investigate the effects that a lumber mill is having on the environment. What they find is a cavalcade of wildlife mutations and an even more frightening series of grisly human deaths. A research expedition led by a local Native American (Armand Assante) uncovers the reign of terror of a large and very angry mutant bear. (jakelijan virallinen teksti)
