Horror film from the year 1958. Originally known as The Trollenberg Terror. At the remote Alpine village of Trollenberg, someone or something is killing off mountain climbers. The culprits turn out to be an army of one-eyed, tentacled beasts from outer space, who hide themselves in a radioactive cloud. Crawling along like snails, these horrific creatures attempt to neutralize their human foes by pumping a freezing fog at their pursuers. It matters not at all that some of the locals have been mentally enslaved by the monsters. It's up to American scientist Alan Brooks to save the day.
