In the aftermath of epic cosmic conflicts and reshaped realities, the world finds itself guarded by a trio of powerful female heroes, each with unique abilities that make them formidable on their own but nearly unstoppable when united. Carol Danvers, known as Captain Marvel, patrols the vast expanse of the universe, ever vigilant against interstellar threats with her incredible powers of flight, strength, and energy manipulation. On Earth, Monica Rambeau, a former Air Force pilot who was imbued with energy-based powers after an otherworldly encounter, grapples with her role as a protector while delving deeper into the nature of her abilities. Kamala Khan, a teenage girl who idolizes Captain Marvel, discovers her own polymorphic powers that allow her to stretch and change shape, taking up the mantle of Ms. Marvel to defend her community.

As global stability wavers under the pressure of a new menace, the paths of the three heroes converge. Their initial interactions are marked by a clash of personalities and methodologies, complicated by their differing experiences and views on heroism. However, they must learn to put aside their differences and collaborate in order to unravel a mystery that ties their powers and pasts together. As they investigate, they uncover a conspiracy that threatens the fabric of the universe, leading them to confront questions about the source and limits of their own powers, and their responsibilities to the world and each other. Their journey will test their individual limits and forge a bond that redefines what it means to be a Marvel.
