A year has passed since the first superheroes appeared, and now they've formed the first superhero team: The Minutemen.

As the world struggles to adapt to the presence of superpowered people in its midst, extremist groups form. One group worships them, while another seeks to eliminate what they view as a threat to a pure human race.

Meanwhile, forces within the government clash over how to address the growing superhuman population: do they allow superheroes to continue to exist, or will the heroes find themselves on the wrong side of the law?
