In 'X - Men Days of Future Past Story', the main idea is to fix a broken future. The future is full of despair as the Sentinels have become an all - powerful force. They can adapt to any mutant power, making them extremely difficult to defeat. Wolverine's time - travel mission is crucial. He goes back to a time when the X - Men were just starting to form. There, he has to deal with the young and troubled versions of the main characters. Professor X is dealing with his own mental issues and Magneto is more radical than ever. Wolverine has to bring them together and make them realize the importance of their combined efforts. By changing the past, they aim to create a future where mutants and humans are not at war and the Sentinels are never created.
