A Sound of Thunder

In 2055 in downtown Chicago, an elite travel agency, Time Safari Inc., has cornered the lucrative time-traveling market. For a price, rich adventurers can stir their dormant killer instincts by booking safaris back to the Prehistoric age to hunt real, live dinosaurs. There are only three essential rules: Don’t change anything in the past; don’t leave anything behind; and most important, don’t bring anything back. The slightest alteration might impact the existing course of evolution in ways that no one can imagine.

Time Safari Inc. is the hottest ticket in town…. until the unthinkable happens. Someone breaks the rules. And evolution runs off its tracks. Only two people guess what might be happening: Dr. Travis Ryer (Edward Burns), who leads the expeditions into the past, and Dr. Sonia Rand (Catherine McCormack), the physicist who developed the technology that makes these journeys possible.

Threatened on all sides and fast running out of time, Ryer and Rand must find a way to go back and correct whatever catastrophic error was made, to save themselves and the human race from certain extinction. But as each new wave of change rolls forward from the Prehistoric past, their world continues to collapse all around them.

Based on a short story by award-winning author Ray Bradbury.
