A "cure" for mutancy threatens to alter the course of history. A short time after "X2," the world is rocked by the unveiling of a new medicine that is designed to cure mutants. This sends shockwaves through the mutant community as various mutants receive the news differently. Some see it as salvation and a way to be 'normal'. Others see it as deeply offensive and a way for humans to control mutants. This prompts Magneto and the Brotherhood to step up their terrorist activities and only the X-Men can stand in their way.

Meanwhile, the X-Men face their own crisis. Jean Grey, thought to be killed in the last film, is resurrected, but in a terrifying new form. Despite almost unlimited power, she suffers from a split personality that only Professor Charles Xavier can control. However, her darker more primal side, called Phoenix, has emerged and wreaks havoc. What will happen when Cyclops, Xavier, and Wolverine try to come to her aid? And what will happen when Magneto attempts to sway her to his cause?

I don't think you should copy summaries either, raatbaki_4u, unless you post what you think about the movie along with it. Besides, I've not seen the movie you're talking about. Niether has anyone I know. So, you're going to have to tell me if it's good or not, cause I'll take advice from anyone here.
