Synopsis by Mark Deming
The crew of the Voyager struggle to find a way to bring harmony to their sworn enemies in this episode of the sci-fi television series Star Trek: Voyager. While out on a scouting mission, Chakotay (Robert Beltran) and Ensign Kaplan (Susan Patterson) receive a distress call from a nearby planet. Chakotay and Kaplan answer the call, but are attacked by angry aliens shortly after landing. Kaplan is killed, but Chakotay is rescued by another band of aliens led by Riley (Lori Hallier); Riley explains that she and the other residents of the planet were alien refugees who had formed a commune until infighting destroyed their dream. After Riley and her friends are brought aboard the Voyager, it's discovered their story isn't quite true; Riley and company were actually assimilated by the Borg years before, and escaped to the planet after their ship was destroyed in a storm in space. Since then, their numbers have shrunk through violent conflicts among themselves, and the battles do not end once they board the Voyager. Star Trek: Voyager 159: Unity first aired on February 12, 1997.
