In the near future, a series of mysterious power surges threatens the stability of Earth's energy systems and endangers human life. The U.S. Space Command believes the surges are coming from the Lima Project, an initiative that lost contact with Earth years ago while endeavoring to find intelligent life at the edge of the solar system. The project was led by esteemed astronaut H. Clifford McBride, who is also the father of renowned astronaut Roy McBride. With the world on the brink of catastrophe, Roy is recruited for a top-secret mission to Mars, where he is tasked with sending a message to his father in hopes of stopping the surges.

Roy embarks on a perilous journey that takes him to the Moon and then to Mars, traversing a future where space travel has become more commercial, yet still harbors numerous dangers, both human and natural. As he travels, Roy grapples with his complex feelings about his absent father and his own place in the world. The odyssey serves as a path not only towards a potential global salvation but also towards personal discovery and confrontation with the vast, often unforgiving expanse of space.
