A HOLLYWOOD LEGEND'S LAST MOVIE – ABOUT HUMANKIND'S FIRST MISSING LINK ENCOUNTER.The Abominable Snowman of the Himalayas. Bigfoot of the Pacific Northwest. Few claim to have seen these links to our primitive past. But when a wild half-man/half-ape emerges from his countryside cave, TV cameras are there to observe the event – and the ensuing terror!People call him Trog, short for a prehistoric cave dweller known as the troglodyte. To a determined anthropologist (Joan Crawford in her final film role), he's the scientific discovery of the age. To others, he's walking death. A grocer is impaled on a meat hook, a car is tossed aside like a twig, a child is kidnapped – all after local resident Sam Murdock (Michael Gough) prods the brute into a blind rampage. In true horror tradition, the world's Murdocks leave no doubt who the real savages are ... but what will become of he who is part-man, part-monster, all Trog!
