Eckels is goes to a place where they have a time machine and he is paying the amount of money he needs to do it and meets Travis his tour guide. Travis is in the green and Eckels is in the red and the guy at the counter is in Blue.
Eckels, Travis, Lesperance the assistant and 2 other hunters Billings and Kramer travel back to the past to kill certain dinosaurs, while doing so Eckels tryed shooting a random dinosaur and Travis got mad and told him that anything he kills that are not dotted with paint may change the future so only shoot the ones with spots on them.
Eckels really wanted to kill a T-rex but when one T-rex started coming to him at full speed he went hyper and ran off the path that he was not supposed to run off on. This dinosaur had a paint spot on him and because Eckels ran off the path and the other 2 hunters were shocked and couldn't move Travis and Lesperance had to kill the dinosaur.
Eckels and everyone else travels back safely from the past but things are different now. Like the guy at the desk is different the way they write and the language is different. And everyone is in shock because of this.
Then Eckels noticed on his shoe that there was a nice butterfly that he killed from the past and that's why the future is different is because he killed a butterfly from the past, all since he stepped off the path.
Since Eckels did what he did and killed a animal from the past and changed the future Travis was mad and told Eckels if anything happens he will kill him and something did happen so Travis killed Eckels. THE END.
