In the year 2055, the rich are able to travel back in time and hunt a live dinosaur for a huge price. Sonia Rand has developed a machine that can take people back in time. Charles Hatton has taken this technology and opened a business know as Time Safari. Anyone with the money can travel back millions of years and shoot a dinosaur. Dr. Travis Ryer leads his team together with the big game hunter on a floating walkway to a spot where they can kill the dinosaur. The trip protocol is that they must stay on the walkway and not disturb the land or anything creature around them. Unfortunately for the human race, one hunter steps on and kills a butterfly. This insignificant act starts off major consequences to the earth's climate and creates new species of animal life. The course of evolution as we know it is now being changed by time waves. Travis and Sonia try to stop the changing process before it becomes permanent and man becomes extinct.
