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.
