The movie opens in the X-Mansion as the most recent set of mutants graduate and old X-Men reunite for the first time in years. We see people like Logan who recently got his memories back thanks to a serum Bruce Banner created, Cyclops who after being left by Jean Grey who is missing is now married to Emma Frost, Beast who after creating the cure for cancer is now a billionaire, Nightcrawler who rejoined the circus he belonged to before the X-Men, and more. Members like Colossus, Magneto, and Kitty Pryde did not return for a number of reasons. Kitty Pryde is currently in India trying to clear her mind now that Peter Parker is with Gwen Stacy, Colossus is working with the X-Force, and Magneto is looking for a way to stop aging. The movie ends with Cyclops and Logan visiting Charles Xavier's grave and saying goodbye. This isn't the end of the X-Men films in this universe but it is the end of the team we've been following. In the next X-Men film we're going to start fresh with new and familiar members.
