Kang the Conqueror is freed from prison by his alternate timeline look-a-likes and attempts to conquer the world once again. This time he traps the Avengers in a temporal void to keep them from getting in the way of his plans. Now a new team of heroes (Spider-Man, War Machine, Wolverine, Iron Fist, Luke Cage and the Thing) must band together to stop the cross-temporal onslaught.

The Avengers arrive on the Kree homeworld of Hala, but find that they aren't exactly welcome there - even with Captain Marvel on their side.
