A scientist perfects a machine that he claims can predict earthquakes. The scientist, David Conway (William Leslie)predicts that a massive quake will strike California in 24 hours, and he is proven correct.
Soon earthquakes are happening everywhere and it become obvious that something is causing more than just the usual run of ground movements.
Conway and his assistant Laura Hutchinson (Kathryn Grant) set up base in the Carlsbad Caverns to try and find out what is happening. By accident they discover a rock which grows and expands then explodes. This turns out to be the culprit. They name it Element 112.
From then on it is a race against time to stop Element 112 from destroying the entire world. This is a fun but sometimes talky film. However, it's not a bad way to kill 64 minutes. I liked it, and the Mill Creek print is beautiful and in the correct aspect ratio.
