They crush all that stand in their path!

A giant meteor crashes to Earth near the small town of San Angelo and local geologist Ben Gilbert (Phil Harvey, The Deadly Mantis) brings a fragment back to his lab for testing. Shortly afterwards, fellow geologist Dave Miller (Grant Williams, The Leech Woman) arrives to find the lab filled with rocks ... and Ben is dead ... his body turned completely to stone!

Now in a desperate race against time, Dave and Professor Arthur Flanders (Trevor Bardette, Death Valley Days) must unlock the secret of the deadly rocks from outer space before they turn the world to stone and destroy mankind! Also featuring Lola Albright (Peyton Place), William Schallert (The Man From Planet X), and Troy Donahue (Monster On The Campus), The Monolith Monsters ratchets up the "tension and suspense ... and the actors really put it across to the viewer, creating a very compelling film" (The Telltale Mind)!
