Years from now, Earth will make first contact with an alien civilization, the Newcomers. Initially quarantined, they're eventually integrated into human society, but face a new kind of discrimination. A Newcomer police officer, Sam Francisco, is paired with a veteran, Matthew Sykes, who harbors racist views. As they investigate the Newcomer underworld and its leader, William Harcourt, their animosity evolves into respect.
