In the remote Scottish highlands, army exercises are disturbed by violent earth tremors and an explosion which kills one soldier and badly burns another. Scientists are called in to investigate the great chasm left by the explosion and soon discover that an enormous blob of radioactive slime lurks within it. But worse is to come - the slime is capable of movement and begins to venture out above ground in search of more radioactivity, threatening to destroy anything and anyone in its path!
