The Colorado prairie has become a graveyard. Mutilated cattle, their organs surgically removed, litter the high country. Is this the gruesome work of a Satanic cult? Of extraterrestrials? Of conspirators who arrive and leave in mysterious black helicopters? The locals are terrified – and it falls to their new sheriff (JoBeth Williams, Poltergeist) and a troubled cop (Robert Urich, Spenser: For Hire) to unravel an eerie skein of deception and danger to discover the stunning truth. This paranoia-fueled thriller from writer/director Alan Rudolph (Welcome To L.A., Afterglow) boasts a stellar supporting cast and spectacular, spooky cinematography that pulls viewers deep inside the mystery. And here's the scariest thing of all: Endangered Species took its inspiration from real-life events.
