Every detective has one criminal he wants to bring to justice—the one who skates around the edges of the underground world, but always has an alibi and can't be pinned down for a single crime. For LAPD Detective Sean Riker, that criminal is Mitchell Yates. Riker thinks he finally has Yates and decides to pull him in for questioning. Instead, Yates saves Sean's life when he takes a bullet to the shoulder. The shooting hasn't stopped and escape routes are blocked. Yates does the only thing he can. Transports Riker to his HOME—a manmade satellite orbiting Earth. Now Riker faces a choice—Remain with the LAPD...or join the Keepers' mission.

Detective Sean Riker leaves the LAPD and joins his lover, Yana, who belongs to a group called the Peace Keepers. Their mission is to help the galaxy exist in unity and they do whatever necessary to further their cause. Their base is a massive satellite orbiting Earth and their adventures are dangerous and difficult. Sean and Yana run into hazardous situations and their battles run the gamut from murderous aliens to a race of kidnappers. A vindictive former foe shows up to create problems, too. Join them as they struggle to save the universe and their relationship.
