In roughly a millennium, the Earth's ozone will die.

The year is 2020, and five friends, formerly known as the Five Brats, or T5B, are called upon the United States Marines to go on a space mission to see if Mars is habitable to help save the Earth from certain doom.

Once aboard the U.S.S. Frontier, the spaceship set to take them to Mars for their two-year mission, they uncover a conspiracy so deep within the U.S. government that it spans from the ground up all the way to their starship.

With no one to trust, time running out, and themselves as targets, they must stop the plot and save humanity in more ways than one.
