After a comet passes the Earth it causes a cataclysmic storm. Only a disbanded government unit with a secret weather-manipulating weapon can try to stop it.

Small town in the Wild West is attacked by poisonous snakes.

Two millennia ago, a Lybian king has a basilisk (snake-shaped dragon), which petrifies people, subjected to the same fate with a golden scepter during a solar eclipse. Both these and several victims are dug up by modern archaeologist Harrison 'Harry' McColl's expedition. Despite a cryptic warning from tribal locals, everything goes to his Colorado university's museum. It's all exhibited during another eclipse, which leads to the monster reviving. Harry and some of his friends must try to petrify the monster again.
