Eckels arrives at Time Safari Inc. to hunt a dinosaur. But since Time Safari Inc. has a time machine, they can hunt any animal they want.
The 5 hunters including Eckels get out and go to the time zone where their T-Rex that they are hunting is supposed to be in.
The hunters encounter the T-Rex and all the hunters shoot at the dinosaur except Eckels, he runs away to hide in the time machine.
Welcome to Tyme Safery Inc.
The hunters eventually kill the T-Rex and go back to the time machine hoping that no one had changed anything in the future.
The hunters are in the time machine adn they are all nervous and probably angry at Eckels because he might have changed something in the future like a animal species or something important that was already in history.
When they return to the office, Travis and Eckels notice changes such as the spelling and that Deutscher won the election. Then we hear the sound of thunder, which is a bullet going into Eckels shot by Travis.
