Chakotay responds to a distress call, and discovers a group of different species, many of which originate from the Alpha Quadrant, living on a planet stricken by conflict. After Chakotay learns that they are all de-assimilated Borg, a group of colonists make a very unorthodox and dangerous request of Voyager.

The request: To activate the generator on the badly damaged Borg cube that will link all the ex BOrg as a collective.

Chakotay has to become linked to the ex Borg, to allow them to heal him from injuries sustained in a fight on the planet.

They later use the link to control him to turn on the generator in the Borg cube; this unifies the ex Borg, who then command the cube to self destruct, once Chakotay and the away team are safely on board Voyager.

This is one of my all time favorite Voyager episodes.

It represents a first encounter with the Borg for Voyager, unless you count when they saw a dead Borg on a planet a few episodes ago.
