Brie Larson stars as Carol Danvers, aka Vers, aka Captain Marvel, an ultra-powerful warrior for an alien race called the Kree, from the capital planet Hala, part of an elite group of warriors called Starforce, who are doing battle with the fearsome, shape-shifting Skrulls, who have the power to impersonate other living beings, with a notable limitation in memories. She is haunted by her own memories of a strange time and place, when she was a pilot in the United States Air Force, which she ends up learning more about when she ends up jettisoned on Earth in 1995. After an explosive skirmish and her high-powered suit catches the interest of the agents of S.H.I.E.L.D., she meets the initially skeptical Nick Fury (Samuel L. Jackson), and begins her search for the light-speed engine, another object in Vers’s memories, that both civilizations want to get their hands on first.  It is on Earth that she begins to put the pieces of her memory and former life there back together, reuniting with old friends in her old stomping grounds.  She also begins to discover more about her mission, what is being fought for, and the nature of the vicious Kree-Skrull war that she never knew about.  Unfortunately, the Skrulls, led by Talos, are in hot pursuit on a planet completely unaware and unprepared for the arrival of such high-powered beings.
