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.

Harry and some of his friends must try to petrify the monster again.
