In the plot we have internal and external conflict. The conflict happens in the rising action in between introduction and the climax. Usually we have few characters in the story and some time conflict between them to. One side always strong and always win, another week and definitely going to lose. Without conflict I think so the story wouldn't be interesting for us to read. Az more conflict happens  in the story az more it hold a reader's interest to see what going to happend next and next and untill you finnish holl book.
