Air Force Lieutenant General Mark Naird is promoted to full four-star general and is hoping to take over as the Chief of Staff of the Air Force. 

But he is appointed as the first Chief of Operations of the newest United States military branch which has branched from the Air Force, led by his rival, General Kick Grabaston. 

His family, including daughter Erin and wife Maggie, are relocated to Wild Horse, Colorado so that he can work at the new base there. 

One year later, the Space Force is about to launch a new satellite called Epsilon 6 into orbit.  But he has to take permission from the government.

The Space Force is disorganized and fledgling, Mark is constantly bombarded by obstacles and adversaries, Erin detests her new home, and Maggie is now in prison. 

Against the advice of his advisors and scientists, including Space Force scientist Dr. Adrian Mallory, Mark orders the launch of Epsilon 6.

Despite initial concerns, and in front of a delegation of prominent members of Congress, Epsilon 6 successfully reaches orbit. 

Later that night, Mark and Adrian celebrate for the successful Launch of the spacecraft. And spent great time together.

Mark, observing Epsilon 6 through a telescope, sees a massive Chinese spacecraft intentionally clip the solar panels, the satellite's only power source, putting Epsilon 6 in jeopardy.
