Lavalantula

After a dormant volcano erupts miles outside of Los Angeles, something within the molten hot lava is awakened. Birthed from the bowels of the Earth itself, arachnid-like creatures with an obsidian-black exoskeleton swarm out. One man, COLTON WEST, a washed-up, former A-list action star, suddenly finds himself the real life hero as he's forced to use his onscreen characters' know-how to save the entire city from being victims to the most horrifying villains you couldn't write any better.
