Eckels meets his Safari Guide, Mr.Travis, his assistant, Lesperance, two other hunters, Billings and Kramer.
The five men in the machine, including Eckels, were talking about ow things could change if they set off the road/path.
Once they all gt where they needed to go from the time machine, they saw the T- rex. They were all quiet getting ready to shoot it. Eckels panics and freaks out.
The T - rex notices that they were there so the T- rex attacks, and the hunters start shooting. Then, the T- rex dies.
Travis notices that Eckels left the path before arriving to the machine and gets mad at him about it. Travis tells him to go remove the bullets from the T- rex. They go back home and notice some differences.
Eckels finds out that he killed a butterfly and that Deutscher was elected to be president. Travis had warned Eckels of shooting him if there were changes. Travis shoots Eckels. There was a sound of thunder.
