For those eternal intergalactic enemies, the merciless Kree and the shape-changing Skrulls, have gone to war, and our planet is situated on the front lines! Can Earth's Mightiest Heroes, the Avengers, bring about an end to the fighting before humanity becomes a casualty of war? And what good are even a dozen super-powered champions against the vast military machines of two of the great empires of the cosmos? The key to victory lies with the expatriate Kree Captain Mar-Vell and his human host, honorary Avenger sidekick Rick Jones!
